9db630b48a HID: add multi-input quirk for NextWindow Touchscreen.
These touchscreens are mounted onto HP TouchSmart and the Dell Studio One
19. Without a quirk they report a wrong button set and the x/y coordinates
through ABS_Z/ABS_RX, confusing the higher levels (most notably X.Org's
evdev driver).

Device id 0x003 covers models 1900, 2150, and 2700 [1] though testing could
only be performed on a model 1900.

5b915d9e6d HID: fixup quirk for NCR devices
NCR devices are terminally broken by design -- they claim themselves to contain
proper input applications in their HID report descriptor, but behave very badly
if treated in standard way.

According to NCR developers, the devices get confused when queried for reports
in a standard way, rendering them unusable.

NCR is shipping application called "RPSL" that can be used to drive these
devices through hiddev, under the assumption that in-kernel driver doesn't
perform initial report query.
If it does, neither in-kernel nor hiddev-based driver can operate with these
devices any more.

Introduce a quirk that skips the report query for all NCR devices. The previous
NOGET quirk was wrong and had been introduced because I misunderstood the nature
of brokenness of these devices.

affbb8c6e6 HID: support larger reports than 64 bytes in hiddev
hiddev userspace driver uses a rignbuffer to store the parsed usages
that should be returned through read(). This buffer is 64 bytes long,
which is sufficient for queueing single USB 1.0 low-speed report, which
is of maximum size 48 bytes.

There are however USB HID devices which are full-speed USB devices, and
therefore they are free to produce reports 64 bytes long. This is correctly
handled by HID core, but read() on hiddev node gets stuck forever, because
the ring buffer loops infinitely (as it is exactly 64 bytes long as well),
never advancing the buffer pointer.

Plus, the core driver is ready to handle highspeed devices, so we should be
able to handle reports from such devices in the hiddev driver as well, which
means we need larger ringbuffer.

0810b51170 HID: Support new variants of Samsung USB IR receiver (0419:0001)
This patch extends the existing Samsung IrDA (0419:0001) quirk file with newly
reported variants:

* New device variants with 203 byte and 135 byte report descriptors were
  reported to be recognized incorrectly. This patch adds an autodetection for
  those two, using report descriptor size to enable new quirks.

* Any other unknown 0419:0001 variants will now be treated without any quirk
  flags (i.e. IGNORE_HIDINPUT/HIDDEV_FORCE will not be set by default anymore).

More details:

1. Descriptor size 184 bytes ("Satelco bundled remote")
Already supported since kernel 2.6.25 (my old patch).

2. Descriptor size 203 bytes ("Optronix remote")
This receiver mostly works with the regular HID input driver. Only when some
keys are released, another spurious key press event is interpreted due to
incorrect array ranges. According to HID 1.11, section 6.2.2.5, arrays should
return a 0 value when no control is asserted, and ranges should go from 1 to
the number of elements. The patch clips the value with a logical range from
1..15 (instead of originally 0..18).

Ticket with more information available at
https://bugs.launchpad.net/bugs/326986

3. Descriptor size 135 bytes ("Gotview remote")
This receiver has a similar issue than the previous one, i.e. it mostly works
with regular HID input, except some key press events get stuck on key release.
The patch clips the array value from 1..14 (instead of originally 0..17).

Ticket with more information available at
http://bugs.archlinux.org/task/15216

4. Other unknown variants (found one report with 218 bytes,
   but no further information about issues)

For such unknown variants we should refrain from changing any device flags.
Currently, HIDINPUT is suppressed and HIDDEV is enforced (because in 2.6.25 the
quirk table did not yet allow differentiating variants and we
did not expect variants either). Now we should be as strict as
possible and enable it only for the first variant above.

* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config

cd667ce247 HID: use debugfs for events/reports dumping
This is a followup patch to the one implemeting rdesc representation in debugfs
rather than being dependent on compile-time CONFIG_HID_DEBUG setting.

The API of the appropriate formatting functions is slightly modified -- if
they are passed seq_file pointer, the one-shot output for 'rdesc' file mode
is used, and therefore the message is formatted into the corresponding seq_file
immediately.

Otherwise the called function allocated a new buffer, formats the text into the
buffer and returns the pointer to it, so that it can be queued into the ring-buffer
of the processess blocked waiting on input on 'events' file in debugfs.

'debug' parameter to the 'hid' module is now used solely for the prupose of inetrnal
driver state debugging (parser, transport, etc).

a635f9dd83 HID: use debugfs for report dumping descriptor
It is a little bit inconvenient for people who have some non-standard
HID hardware (usually violating the HID specification) to have to
recompile kernel with CONFIG_HID_DEBUG to be able to see kernel's perspective
of the HID report descriptor and observe the parsed events. Plus the messages
are then mixed up inconveniently with the rest of the dmesg stuff.

This patch implements /sys/kernel/debug/hid/<device>/rdesc file, which
represents the kernel's view of report descriptor (both the raw report
descriptor data and parsed contents).

With all the device-specific debug data being available through debugfs, there
is no need for keeping CONFIG_HID_DEBUG, as the 'debug' parameter to the
hid module will now only output only driver-specific debugging options, which has
absolutely minimal memory footprint, just a few error messages and one global
flag (hid_debug).

We use the current set of output formatting functions. The ones that need to be
used both for one-shot rdesc seq_file and also for continuous flow of data
(individual reports, as being sent by the device) distinguish according to the
passed seq_file parameter, and if it is NULL, it still output to kernel ringbuffer,
otherwise the corresponding seq_file is used for output.

The format of the output is preserved.

0f6f4319a7 HID: fix hid-ff drivers so that devices work even without ff support
Currently, the hid-*ff force feedback drivers, which claim the blacklisted
device on a HID bus, are only compiled in if the user selects force feedback
support.

However we want the device to be supported even when the kernel is configured
without force feedback.

This patch fixes the drivers in a way that they get compiled even if force
feedback is turned off; all the force feedback support code is compiled out in
such case, and the driver works as a usual driver on HID bus, claiming and
initializing the device, making it operational without FF effects.

	retval = usb_register_dev(usbhid->intf, &hiddev_class);

here you open a window during which open can happen

	if (retval) {
		err_hid("Not able to get a minor for this device.");
		hid->hiddev = NULL;
		kfree(hiddev);
		return -1;
	} else {
		hid->minor = usbhid->intf->minor;
		hiddev_table[usbhid->intf->minor - HIDDEV_MINOR_BASE] = hiddev;

and will fail because hiddev_table hasn't been updated

The obvious fix of using a mutex to guard hiddev_table doesn't work because
usb_open() and usb_register_dev() take minor_rwsem and we'd have an AB-BA
deadlock. We need a lock usb_open() also takes in the right order and that leaves
only one option, BKL. I don't like it but I see no alternative.

Once the usb_open() implements something better than lock_kernel(), we could also
do so.

0361a28d3f HID: autosuspend support for USB HID
This uses the USB busy mechanism for aggessive autosuspend of USB
HID devices. It autosuspends all opened devices supporting remote wakeup
after a timeout unless

- output is being done to the device
- a key is being held down (remote wakeup isn't triggered upon key release)
- LED(s) are lit
- hiddev is opened

As in the current driver closed devices will be autosuspended even if they
don't support remote wakeup.

The patch is quite large because output to devices is done in hard interrupt
context meaning a lot a queuing and locking had to be touched. The LED stuff
has been solved by means of a simple counter. Additions to the generic HID code
could be avoided. In addition it now covers hidraw. It contains an embryonic
version of an API to let the generic HID code tell the lower levels which
capabilities with respect to power management are needed.

60aa49243d Rationalize fasync return values
Most fasync implementations do something like:

     return fasync_helper(...);

But fasync_helper() will return a positive value at times - a feature used
in at least one place.  Thus, a number of other drivers do:

     err = fasync_helper(...);
     if (err < 0)
             return err;
     return 0;

In the interests of consistency and more concise code, it makes sense to
map positive return values onto zero where ->fasync() is called.

96fe2ab830 HID: fix waitqueue usage in hiddev
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list
to 'empty' but to zero.

prepare_to_wait() will not enqueue the descriptor to the waitqueue and
finish_wait() will do list_del_init() on a list head that contains
NULL pointers, which oopses.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".

The prior code used an unconditional add_to_waitqueue() which didn't
care about the wait descriptor's list head and enqueued the thing
unconditionally.

The new code uses prepare_to_wait() which DOES check the prior list
state, so use DEFINE_WAIT instead.

48e7a3c95c HID: fix incorrect free in hiddev
If hiddev_open() fails, it wrongly frees the shared hiddev structure
kept in hiddev_table instead of the hiddev_list structure allocated
for the opened file descriptor.  Existing references to this structure
will then accessed free memory.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".

daedb3d6a9 HID: move tmff and zpff devices from ignore_list to blacklist
The devices handled by hid-tmff and hid-zpff were added in the
hid_ignore_list[] instead of hid_blacklist[] in hid-core.c, thus
disabling them completely.

hid_ignore_list[] causes hid layer to skip the device, while
hid_blacklist[] indicates there is a specific driver in hid bus.

Re-enable the devices by moving them to the correct list.

35cfd1d964 HID: blacklist Powercom USB UPS
For quite some time users with various UPSes from Powercom were forced to play
magic with bind/unbind in /sys in order to be able to see the UPSes.  The
beasts does not work as HID devices, even if claims to do so.  cypress_m8
driver works with the devices instead, creating a normal serial port with which
normal UPS controlling software works.

The manufacturer confirmed the upcoming models with proper HID support will
have different device IDs.  In any way, it's wrong to have two completely
different modules for one device in kernel.

Blacklist the device in HID (add it to hid_ignore_list) to stop this mess,
finally.

Many people get it wrong and add device IDs into hid_blacklist instead
of hid_ignore_list. Let's put a little comment in place.

0fb21de079 HID: adjust report descriptor fixup for MS 1028 receiver
Report descriptor fixup for MS 1028 receiver changes also values for
Keyboard and Consumer, which incorrectly trims the range, causing correct
events being thrown away before passing to userspace.

We need to keep the GenDesk usage fixup though, as it reports totally bogus
values about axis.

Commit 079034073f ("HID: hiddev cleanup -- handle all error conditions
properly") by mistake removed proper initialization of hid->hiddev pointer
in hiddev_connect() in case usb_register_dev() succeeds for the hiddev node.
Put it properly back in place.

011b15df46 USB: change interface to usb_lock_device_for_reset()
This patch (as1161) changes the interface to
usb_lock_device_for_reset().  The existing interface is apparently not
very clear, judging from the fact that several of its callers don't
use it correctly.  The new interface always returns 0 for success and
it always requires the caller to unlock the device afterward.

The new routine will not return immediately if it is called while the
driver's probe method is running.  Instead it will wait until the
probe is over and the device has been unlocked.  This shouldn't cause
any problems; I don't know of any cases where drivers call
usb_lock_device_for_reset() during probe.
