3a6f82f7a2 HID: add dynids facility
Allow adding new devices to the hid drivers on the fly without
a need of kernel recompilation.

Now, one can test a driver e.g. by:
echo 0003:045E:00F0.0003 > ../generic-usb/unbind
echo 0003 045E 00F0 > new_id
from some driver subdir.

6bbe586fd4 HID: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

08ef08ee8c HID: automatically call usbhid_set_leds in usbhid driver
This patch (as1146c) makes usbhid automatically call usbhid_set_leds()
for any device that supports the keyboard boot protocol.

In theory this should be perfectly safe.  BIOSes send the LED output
report as part of their normal device initialization, so any keyboard
device supporting the boot protocol has to be able to handle it.

As a side effect, the hid-dell and hid-bright drivers are no longer
needed, and the Logitech keyboard driver can be removed from hid-lg.

ee8a1a0a1a HID: Apple ALU wireless keyboards are bluetooth devices
While parsing 'hid_blacklist' in the apple alu wireless keyboard is not found.
This happens because in the blacklist it is declared with HID_USB_DEVICE
although the keyboards are really bluetooth devices.  The same holds for
'apple_devices' list.

This patch fixes it by changing HID_USB_DEVICE to HID_BLUETOOTH_DEVICE in those
two lists.

06d2148ed3 HID: unignore mouse on unibody macbooks
In commit a96d6ef34, the mouse interfaces on the unibody macbooks were
put into hid mouse ignore list. This was a little bit too premature
though, as the corresponding bcm5974 changes are scheduled for 2.6.29.

Remove these devices from the ignore list for now, in order to provide at
least basic functionality with the HID driver.

Will be reintroduced in 2.6.29

fa157bdfe8 HID: add quirk entry for no-name keyboard (0x13ba/0x0017)
This patch (as1157) adds a no-name PS/2-to-USB keyboard+mouse adapter
to the hid-dell driver.  (The device shows up with a Product string
saying "Generic USB K/B", nothing more.)  This will force an initial
"Set-LEDs" report to be sent to the device, without which it won't
send any keystroke information.  Several bug reports mentioning this
device have been filed in various forums; the patch should resolve
them.

This is just a temporary stop-gap for 2.6.28.  A later patch for
2.6.29 will introduce a more generic mechanism for "Set-LEDs", making
this change (and the entire hid-dell driver) unnecessary.

022b7024d4 Revert "HID: Invert HWHEEL mappings for some Logitech mice"
This reverts commit 740f370dc6.

It turned out to be correct in the first place: a positive value should
be sent when the wheel is moved to the right, and a negative value when
moved to the left. This is the behavior expected by the Xorg evdev
driver. I must have had a remapping somewhere else in my system when
originally testing this. Testing on another system shows that the
unpatched kernel is correct.

Here is a bug report from Mandriva that brought the problem to my
attention:

c0bd6a4298 HID: remove ignore quirk for MGE UPS devices
This patch reverts the change made four years ago here:
http://www.vg.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-hid-2.4.25-pre7.patch

UPS's made by MGE can be used with usbhid just fine, and by removing the
ignore quirk allows them to be used with HAL so they just work when plugged
in, without needing to be manually configured.

With the ignore quirk in place a user would have to configure NUT before the
UPS could be used, as NUT uses it's own internal USB matching framework
to match against the USB devices, do low level control messages on the
device and then parse the HID tables all in userspace.

This is not needed, as allowing the device to be claimed as a usbhid device
allows it to be used like any other USB UPS device. The devices correctly
advertise the power device page which can be queried for the device state.

I assume the quirk was changed so that people using < libusb 0.1.8 could
still use NUT's internal HID code to manage the UPS.
libusb 0.1.8 was released quite some time ago: 2004-02-11.

This patch does not break NUT as in drivers/libusb.c the device is force
unbound from the kernel driver using usb_detach_kernel_driver_np () where
it can be controlled like normal.

It's implemented to change behaviour in very tiny manner, so that no driver

Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted

86166b7bcd HID: add hidraw interface
hidraw is an interface that is going to obsolete hiddev one
day.

Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.

hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.

Another drawback of hiddev is that it is USB-specific.

hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

46386b5870 HID: introduce proper zeroing of unused bits in output reports
Some HID devices are looking on the unused bits in the HID reports they
receive. This is violating the specification, but we want to make those
devices work. Well-behaving devices are unaffected, as they don't care
about the unused bits.

If bitsused % 8 is 0 all bits in data[] get used and we don't need to
clear anything. Otherwise (bitsused % 8) bits of the last byte get used.
By shifting 1 for (bitsused % 8) bits and subtracting 1 we create a mask
consisting of (bitsused % 8) ones and remaining zeroes. By ANDing we
clear the upper unused bits.

Truncated reports should not be discarded since it prevents buggy

Prior to the regession introduced in 2.6.20, a shorter-than-expected
report in hid_input_report() was passed thru after having the missing
bytes cleared. This behavior was established over a few patches in the
2.6.early-teens days, including commit
cd6104572b.

This patch restores the previous behavior and fixes the regression.

d108d4fe34 HID: zeroing of bytes in output fields is bogus
This patch removes bogus zeroing of unused bits in output reports,
introduced in Simon's patch in commit d4ae650a.
According to the specification, any sane device should not care
about values of unused bits.

What is worse, the zeroing is done in a way which is broken and
might clear certain bits in output reports which are actually
_used_ - a device that has multiple fields with one value of
the size 1 bit each might serve as an example of why this is
bogus - the second call of hid_output_report() would clear the
first bit of report, which has already been set up previously.

This patch will break LEDs on SpaceNavigator, because this device
is broken and takes into account the bits which it shouldn't touch.
The quirk for this particular device will be provided in a separate
patch.

47a80edb1d HID: allocate hid_parser in a proper way
hid_parser is non-trivially large structure, so it should be allocated
using vmalloc() to avoid unsuccessful allocations when memory fragmentation
is too high.
This structue has a very short life, it's destroyed as soon as the report
descriptor has been completely parsed.

This should be considered a temporary solution, until the hid_parser is
rewritten to consume less memory during report descriptor parsing.

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).

With this change all LED enums from the input system get mapped to more
