      HID: zeroing of bytes in output fields is bogus · d108d4fe
      由 Jiri Kosina 提交于 
      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.

      HID: allocate hid_parser in a proper way · 47a80edb
      由 Jiri Kosina 提交于 
      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.

      HID: fix Logitech DiNovo Edge touchwheel and Logic3 /SpectraVideo middle button · 25914662
      由 Jiri Kosina 提交于 
      Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird
non-standard way - it contains multiple reports with the same usage, which
results in remapping of GenericDesktop.X and GenericDesktop.Y usages to
GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the
touchwheel unusable.

The commit 35068976 solved this
in a way that it didn't remap certain usages. This however breaks
(at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210),
which in contrary requires the remapping.

To make both of the harware work, allow remapping of these usages again,
and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we
disable remapping for key, abs and rel events only for this hardware.

      HID: fix broken Logitech S510 keyboard report descriptor; make extra keys work · b55fd23c
      由 Jiri Kosina 提交于 
      This patch makes extra keys (F1-F12 in special mode, zooming, rotate, shuffle)
on Logitech S510 keyboard work.

Logitech S510 keyboard sends in report no. 3 keys which are far above the
logical maximum described in descriptor for given report.

This patch introduces a HID quirk for this wireless USB receiver/keyboard
in order to fix the report descriptor before it's being parsed - the logical
maximum and the number of usages is bumped up to 0x104d). The values are in the
"Reserved" area of consumer HUT, so HID_MAX_USAGE had to be changed too.

In addition to proper extracting of  the values from report descriptor, proper
HID-input mapping is introduced for them.

      HID: fix possible double-free on error path in hid parser · 776c0e96
      由 Jiri Kosina 提交于 
      Freeing of device->collection is properly done in hid_free_device() (as
this function is supposed to free all the device resources and could be
called from transport specific code, e.g. usb_hid_configure()).

Remove all kfree() calls preceeding the hid_free_device() call.

      HID: fix bug in zeroing the last field byte in output reports · 4237081e
      由 Jiri Kosina 提交于 
      d4ae650a introduced zeroing of the
last field byte in output reports in order to make sure the unused
bits are set to 0. This is done in a wrong way, resulting in a
wrong bits being zeroed out (not properly shifted by the field offset
in the report). Fix this.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      由 Tim Schmielau 提交于 
      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).

      由 Jiri Kosina 提交于 
      CONFIG_INPUT_DEBUG is non-existent option, so remove anything depending
on it.

Also, as we have new CONFIG_HID_DEBUG, this should be used on places
where ifdef DEBUG was used before.

      HID: hid debug from hid-debug.h to hid layer · c080d89a

      hid-debug.h contains a lot of code, and should not therefore
be a header.

This patch moves the code to generic hid layer as .c source, and
introduces CONFIG_HID_DEBUG to conditionally compile it, instead
of playing with #define DEBUG and including hid-debug.h.

      hid: quirk for multi-input devices with unneeded output reports · 5556feae
      由 Anssi Hannula 提交于 
      Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports
when enumerating reports on a hid-input device. Add this quirk and
HID_QUIRK_MULTI_INPUT to 0810:0001.

PantherLord Twin USB Joystick, 0810:0001 has separate input reports
for 2 distinct game controllers in the same interface, so it needs
HID_QUIRK_MULTI_INPUT. However, the device also contains one output
report per controller which is used to control the force feedback
function, and we do not want those to appear as separate input
devices as well. The simplest approach seems to be to add a quirk to
skip output reports on 0810:0001, and allow the force feedback
driver to handle those.

      HID: fix pb_fnmode and move it to generic HID · 76398f96
      由 Jiri Kosina 提交于 
      The apple powerbook people are used to switch the pb_fnmode
setting at runtime through writing to sysfs, altering the
module parameter value. This was broken for them in 2.6.20-rc1
when generic HID layer was introduced, as the pb_fnmode flag
was made per-hiddevice, instead of global variable.

This patch moves the pb_fnmode module parameter from usbhid module
to hid module, but apart from that retains backward compatibility
with respect to changing the mode through sysfs.
