      HID: introduce proper dependency of HID_BATTERY on POWER_SUPPLY · 7e69ba7c
      由 Jiri Kosina 提交于 
      ppc6xx_defconfig reveals this:

drivers/built-in.o: In function `hidinput_cleanup_battery': drivers/hid/hid-input.c:351: undefined reference to`power_supply_unregister'
drivers/built-in.o: In function `hidinput_setup_battery': drivers/hid/hid-input.c:338: undefined reference to `power_supply_register'
make[1]: *** [.tmp_vmlinux1] Error 1

The defconfig in question doens't mention either option and kbuild is
genertaing

	CONFIG_HID_BATTERY_STRENGTH=y
	CONFIG_POWER_SUPPLY=m

which is wrong. Put a proper dependency in place.

      HID: make parser more verbose about parsing errors by default · 8c3d52fc
      由 Jiri Kosina 提交于 
      Most of the parsing errors (typically resulting in device not being claimed
by HID subsystem at all) are reported only in debugging mode, which makes
root-causing problems with buggy devices unnecessarily more difficult.

Convert reporting of important HID report descriptor parsing errors to
be reported through hid_err() / hid_warn() instead of dbg_hid().

      HID: hid-input: add support for HID devices reporting Battery Strength · 4f5ca836
      由 Jeremy Fitzhardinge 提交于 
      Some HID devices, such as my Bluetooth mouse, report their battery
strength as an event.  Rather than passing it through as a strange
absolute input event, this patch registers it with the power_supply
subsystem as a battery, so that the device's Battery Strength can be
reported to usermode.

The battery appears in sysfs names
/sys/class/power_supply/hid-<UNIQ>-battery, and it is a child of the
battery-containing device, so it should be clear what it's the battery of.

Unfortunately on my current Fedora 16 system, while the battery does
appear in the UI, it is listed as a Laptop Battery with 0% charge (since
it ignores the "capacity" property of the battery and instead computes
it from the "energy*" fields, which we can't supply given the limited
information contained within the HID Report).

Still, this patch is the first step.

      HID: support primax keyboards violating USB HID spec · f6a04605
      由 Terry Lambert 提交于 
      Primax keyboards with the issue this driver addresses report modifier
keys as in band key events instead of as out of band modifier bits,
resulting in the modifier keys generating key up events immediately
before the keys they are intended to modify.  This driver rewrites
the raw report data from such keyboards into USB HID 1.11 compliant
report data.  It only matches the USB vendor and product IDs for the
keyboard it has been tested on. Since there are several keyboards,
notably a number of laptops and folding USB keyboards known to have
similar unresolved problem reports, the list is expected to grow.

      HID: hiddev: potential info leak in hiddev_ioctl() · 9561f7fa
      由 Dan Carpenter 提交于 
      Smatch has a new check for Rosenberg type information leaks where
structs are copied to the user with uninitialized stack data in them.

In this case, the hiddev_devinfo struct has a two byte hole.

        __u32                      devnum;               /*     8     4 */
        __u32                      ifnum;                /*    12     4 */

      HID: Add full support for Logitech Unifying receivers · 534a7b8e
      由 Nestor Lopez Casado 提交于 
      With this driver, all the devices paired to a single Unifying
receiver are exposed to user processes in separated /input/dev
nodes.

Keyboards with different layouts can be treated differently,
Multiplayer games on single PC (like home theater PC) can
differentiate input coming from different kbds paired to the
same receiver.

Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)
into these two.
