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

Pull HID fixes from Jiri Kosina:

 - revert of the high-resolution scrolling feature, as it breaks certain
   hardware due to incompatibilities between Logitech and Microsoft
   worlds. Peter Hutterer is working on a fixed implementation. Until
   that is finished, revert by Benjamin Tissoires.

 - revert of incorrect strncpy->strlcpy conversion in uhid, from David
   Herrmann

 - fix for buggy sendfile() implementation on uhid device node, from
   Eric Biggers

 - a few assorted device-ID specific quirks

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid:
  Revert "Input: Add the `REL_WHEEL_HI_RES` event code"
  Revert "HID: input: Create a utility class for counting scroll events"
  Revert "HID: logitech: Add function to enable HID++ 1.0 "scrolling acceleration""
  Revert "HID: logitech: Enable high-resolution scrolling on Logitech mice"
  Revert "HID: logitech: Use LDJ_DEVICE macro for existing Logitech mice"
  Revert "HID: logitech: fix a used uninitialized GCC warning"
  Revert "HID: input: simplify/fix high-res scroll event handling"
  HID: Add quirk for Primax PIXART OEM mice
  HID: i2c-hid: Disable runtime PM for LG touchscreen
  HID: multitouch: Add pointstick support for Cirque Touchpad
  HID: steam: remove input device when a hid client is running.
  Revert "HID: uhid: use strlcpy() instead of strncpy()"
  HID: uhid: forbid UHID_CREATE under KERNEL_DS or elevated privileges
  HID: input: Ignore battery reported by Symbol DS4308
  HID: Add quirk for Microsoft PIXART OEM mouse

@@ -190,16 +190,7 @@ A few EV_REL codes have special meanings: 
* REL_WHEEL, REL_HWHEEL:



  - These codes are used for vertical and horizontal scroll wheels,

    respectively. The value is the number of "notches" moved on the wheel, the

    physical size of which varies by device. For high-resolution wheels (which

    report multiple events for each notch of movement, or do not have notches)

    this may be an approximation based on the high-resolution scroll events.



* REL_WHEEL_HI_RES:



  - If a vertical scroll wheel supports high-resolution scrolling, this code

    will be emitted in addition to REL_WHEEL. The value is the (approximate)

    distance travelled by the user's finger, in microns.

    respectively.
