      HID: Multitouch support for the N-Trig touchscreen · 57fd637a
      由 Stephane Chatty 提交于 
      Adds support for multitouch interaction on the N-Trig touchscreen, using the
new ABS_MT_* input constants. Single touch support works as previously. This
code was tested against two versions of the N- Trig firmware: one that supports
dual pen/finger single touch, and one that supports finger multitouch but no
pen at all. Copyright notices that looked wrong were removed, as it seems that
there is only code written in 2009 by Rafin Rubin and Stephane Chatty in this
file.

      HID: add new multitouch and digitizer contants · 89f536cc
      由 Stephane Chatty 提交于 
      Added constants to hid.h for all digitizer usages (including the new multitouch
ones that are not yet in the official USB spec but are being pushed by Microsft
as described in their paper "Digitizer Drivers for Windows Touch and Pen-Based
Computers"). Updated hid-debug.c to support the new MT input constants such as
ABS_MT_POSITION_X.

      Rationalize fasync return values · 60aa4924
      由 Jonathan Corbet 提交于 
      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.

      HID: fix waitqueue usage in hiddev · 96fe2ab8
      由 Johannes Weiner 提交于 
      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 07903407 "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.

      HID: fix incorrect free in hiddev · 48e7a3c9
      由 Johannes Weiner 提交于 
      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.
