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

Pull HID updates from Jiri Kosina:

 1) Patchset from Henrik Rydberg which substantially reduces irqsoff
    latency for all input devices.  In addition to that, Henrik reworked
    multitouch handling in order to reduce runtime memory consumption.

    This patchset touches code in Input subsystem as well.  All the
    changes have been Acked by Dmitry, and we agreed to do it this way
    due to inter-dependencies between the patchset and subsequent
    changes in HID subsystem.

 2) Rework, clenaups and a lot of fixes to picolcd driver by Bruno
    Prémont.

 3) Core report descriptor handling fix which fixes resume issue on some
    devices, by Kevin Daughtridge

 4) hidraw fixes by Alexey Khoroshilov and Ratan Nalumasu

 5) wiimote driver now supports balance board, by David Herrmann.

 6) Other smaller fixes and new device id additions all over the place.

WWhat: /sys/class/hidraw/hidraw*/device/oled*_img
Date: June 2012
Contact: linux-bluetooth@vger.kernel.org
Description:
The /sys/class/hidraw/hidraw*/device/oled*_img files control
OLED mocro displays on Intuos4 Wireless tablet. Accepted image
has to contain 256 bytes (64x32 px 1 bit colour). The format
is the same as PBM image 62x32px without header (64 bits per
horizontal line, 32 lines). An example of setting OLED No. 0:
dd bs=256 count=1 if=img_file of=[path to oled0_img]/oled0_img
The attribute is read only and no local copy of the image is
stored.
