84dcd59495 USB: fix up problems in the vtusb driver
Add range check on buffer sizes passed in from user space
(max is 8*PAGE_SIZE) which will work for the most common
spectrometers even at pages as small as 1K.

Add kref to vst device structure to preserve reference to the
usb object until we truly are done with it.

c0f082c536 USB: ftdi-elan: Always pass usb_bulk_msg() a timeout in milliseconds.
The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be
specified in milliseconds.  The ftdi-elan driver converts milliseconds to
jiffies before passing the timeout to usb_bulk_msg().  This is mostly harmless,
since it will just lead to very long timeouts, but was obviously not the intent
of the original author.

cbc30118d7 usb: vstusb.c : new driver for spectrometers used by Vernier Software & Technology, Inc.
This patch adds the vstusb driver to the drivers/usb/misc directory.
This driver provides support for Vernier Software & Technology
spectrometers, all made by Ocean Optics. The driver provides both IOCTL
and read()/write() methods for sending raw data to spectrometers across
the bulk channel. Each method allows for a configured timeout.

bedf0883cb USB: drivers/usb/misc: Use an IS_ERR test rather than a NULL test
In case of error, the function backlight_device_register returns an
ERR pointer, but never returns a NULL pointer. So a NULL test that may
come after a call to this function should be strengthened by an IS_ERR
test.

The semantic match that finds this problem is as follows:

88d987d6db usb: auerswald: remove driver (obsolete)
This patch removes the auerswald USB driver from the linux kernel
2.6.26.

This driver was included into the kernel mainly to connect to the ISDN
framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile
and moving ISDN support, this connection was never realized, and the
only use of this driver was for device configuration. In the age of DSL,
the demand of ISDN support is getting very low.

Meanwhile, with the advent of libusb, an userspace driver was done for
the device configuration which works fine for linux and mac. (Thanks to
the libusb developers!). The userspace driver is downloadable from the
auerswald web site.

So this driver is obsolete now and has to be removed. Many thanks to all
developers which helped me to bring this driver up and working.

62d104d0de USB: Firmware loader driver for USB Apple iSight camera
Uninitialised Apple iSight drivers present with a distinctive USB ID.
Once firmware has been uploaded, they disconnect and reconnect with a
new ID. At this point they can be driven by the uvcvideo driver. As this
is unique to the Apple cameras and not functionality shared by any other
UVC devices, it makes sense to provide the firmware loading
functionality in a separate driver. This driver will read an isight.fw
file extracted from the Apple driver using the tools at
http://bersace03.free.fr/ift/ and upload it to the camera. It will also
handle the case where the device loses its firmware during hibernation
and must have it reloaded.

bfd3a5a96c USB: Phidget: fix race in device_create
There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.

This patch fixes the problem by using the new function,
device_create_drvdata().  It fixes all 3 phidget drivers, which all have
the same problem.

5fc89390f7 USB: remove PICDEM FS USB demo (04d8:000c) device from ldusb
Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
to use bulk transfer and not interrupt transfer. So I've updated the libusb
based program here (Post #31).
	http://forum.microchip.com/tm.aspx?m=106426&mpage=2

So I believe that the in-kernel ldusb driver will no longer work with the
demo firmware.  It should be removed.

28ffd79c31 USB: usbtest displays diagnostics again
Minor cleanup to the "usbtest" driver, mostly to resolve a regression:
all the important diagnostics were at KERN_DEBUG, so that when the
"#define DEBUG" was removed from the top of that file it stopped
providing diagnostics.  Fix by using KERN_ERROR.  Also:

 - Stop using the legacy dbg() calls
 - Simplify the internal debug macros
 - Correct some test descriptions:
	* Test #10 subcase 7 should *always* stall
	* Test #10 subcase 8 *may* stall
 - Diagnostic about control queue test failures is more informative
 - Fix some whitespace "bugs"

And add a warning about the rude interaction between usbfs ioctl()
and khubd during device disconnect ... don't unplug a device under
test, that will wedge.

f08812d5eb USB: FIx locks and urb->status in adutux (updated)
Two main issues fixed here are:
 - An improper use of in-struct lock to protect an open count
 - Use of urb status for -EINPROGRESS

Also, along the way:
 - Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
   to use usb_unlink_urb whatsoever in this driver, and the old use of
   usb_kill_urb was outright racy (it unlinked and immediately freed).
 - Fix indentation in adu_write. Looks like it was damaged by a script.
 - Vitaly wants -EBUSY on multiply opens.
 - bInterval was taken from a wrong endpoint.

e400b6ec4e vt/vgacon: Check if screen resize request comes from userspace
Various console drivers are able to resize the screen via the con_resize()
hook.  This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's.  One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware.  However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.

To work around this problem, add an extra parameter to con_resize().  This
parameter is ignored by drivers except for vgacon.  If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success.  If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware.  The
latter is the more correct behavior.

With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

d4ead16f50 USB: prevent char device open/deregister race
This patch (as908) adds central protection in usbcore for the
prototypical race between opening and unregistering a char device.
The spinlock used to protect the minor-numbers array is replaced with
an rwsem, which can remain locked across a call to a driver's open()
method.  This guarantees that open() and deregister() will be mutually
exclusive.

The private locks currently used in several individual drivers for
this purpose are no longer necessary, and the patch removes them.  The
following USB drivers are affected: usblcd, idmouse, auerswald,
legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and
usb-skeleton.

As a side effect of this change, usb_deregister_dev() must not be
called while holding a lock that is acquired by open().  Unfortunately
a number of drivers do this, but luckily the solution is simple: call
usb_deregister_dev() before acquiring the lock.

In addition to these changes (and their consequent code
simplifications), the patch fixes a use-after-free bug in adutux and a
race between open() and release() in iowarrior.

0da2f0f164 potential compiler error, irqfunc caller sites update
In 7d12e780e0 David Howells performed
this evolution:
 "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"

He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions.  The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.

Here is the semantic patch that found the occurences
and fixed the problem.

147c5a1733 USB: iowarrior.c: timeouts too small in usb_control_msg calls
The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.

The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.

The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

28ee086d5b backlight: Fix external uses of backlight internal semaphore
backlight_device->sem has a very specific use as documented in the
header file. The external users of this are using it for a different
reason, to serialise access to the update_status() method.

backlight users were supposed to implement their own internal
serialisation of update_status() if needed but everyone is doing
things differently and incorrectly. Therefore add a global mutex to
take care of serialisation for everyone, once and for all.

Locking for get_brightness remains optional since most users don't
need it.

Also update the lcd class in a similar way.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

4b87361d49 USB: u132-hcd/ftdi-elan: add support for Option GT 3G Quad card
ELAN's U132 is a USB to CardBus OHCI controller adapter,
    designed specifically for CardBus 3G data cards to
    function in machines without a CardBus slot.
The "ftdi-elan" module is a USB client driver, that detects
    a supported CardBus OHCI controller plugged into the
    U132 adapter and thereafter provides the conduit for
    for access by the "u132-hcd" module.
The "u132-hcd" module is a (cut-down OHCI) host controller
    that supports a single OHCI function of the CardBus 
    card inserted into the U132 adapter.

The problem with the initial implementation is that when
the CardBus card inserted into the U132 adapter has multiple
functions (and a CardBus card can support up to 4 functions),
it was the first function that was arbitrarily choosen.

The first batch of 3G cards tested, like the Merlin Qualcomm
V620, have two functions each supporting a seperate USB OHCI
host controller, of which it was that first function that is
wired up to the 3G modem.

Then along comes the Vodafone Mobile Connect 3G/GPRS data card,
aka "Option GT 3G Quad" as printed on it's rear or "Option N.V.
GlobeTrotter Fusion Quad Lite" as read with "lspci -v". And it
has the meaningful functionality in the second CardBus function.

That presents a problem because it was the "ftdi-elan" module
alone that knows how to communicate to the embedded CardBus slot
and the "u132-hcd" module alone that knows how to access the
pcmcia configuration and CardBus accessible memory space. And
of course, the information about attached (internally hardwired)
devices is contained within USB configuration embedded somewhere
within the CardBus card.

If only the "u132-hcd" module probe() interface could return a
result code that propagated back to the instigating function
platform_device_register() then the "ftdi-elan" module could
try an alternative CardBus function.     However in spite of
the recent changes to the drivers/base/ routines that moved 
device_attach() from bus_add_device() to bus_attach_device()
both of those routines lose the "failed to attach" 0 result
code and thus the calling routine, namely device_add() is
incapable of propaging the "failed to attach" condition back
to platform_device_add() and consequently back to the caller
of platform_device_register()

Experiments show that patching bus_attach_device() to return
ENODEV fails with the kernel locking up very early during
boot. But, however, if the patch is restricted to calls from
platform_device_add() then it does seem to work.

Unfortunately, until the kernel's drivers/base is properly
modified to propagate -ENODEV back to the caller of
platform_device_register(), it is necessary to "fix" the
"ftdi-elan" module by importing knowledge from the 
"u132-hcd" module. This is the reason for the duplicated
functionality introduced in this patch.

519ab5f2be ACPI: video: Add dev argument for backlight_device_register
This patch set adds generic abstract layer support for acpi video driver to
have generic user interface to control backlight and output switch control by
leveraging the existing backlight sysfs class driver, and by adding a new
video output sysfs class driver.

This patch:

Add dev argument for backlight_device_register to link the class device to
real device object.  The platform specific driver should find a way to get the
real device object for their video device.

5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls
Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.
