Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid

Pull HID updates from Jiri Kosina:

 - high-resolution scrolling support that gracefully handles differences
   between MS and Logitech implementations in HW, from Peter Hutterer
   and Harry Cutts

 - MSI IRQ support for intel-ish driver, from Song Hongyan

 - support for new hardware (Cougar 700K, Odys Winbook 13, ASUS FX503VD,
   ASUS T101HA) from Daniel M. Lambea, Hans de Goede and Aleix Roca
   Nonell

 - other small assorted fixups

physical size of which varies by device. For high-resolution wheels
this may be an approximation based on the high-resolution scroll events,
see REL_WHEEL_HI_RES. These event codes are legacy codes and
REL_WHEEL_HI_RES and REL_HWHEEL_HI_RES should be preferred where
available.
* REL_WHEEL_HI_RES, REL_HWHEEL_HI_RES:
- High-resolution scroll wheel data. The accumulated value 120 represents
movement by one detent. For devices that do not provide high-resolution
scrolling, the value is always a multiple of 120. For devices with
high-resolution scrolling, the value may be a fraction of 120.
If a vertical scroll wheel supports high-resolution scrolling, this code
will be emitted in addition to REL_WHEEL or REL_HWHEEL. The REL_WHEEL
and REL_HWHEEL may be an approximation based on the high-resolution
scroll events. There is no guarantee that the high-resolution data
is a multiple of 120 at the time of an emulated REL_WHEEL or REL_HWHEEL
event.
