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.

+What: /sys/class/regulator/.../bypass
+Date: September 2012
+KernelVersion: 3.7
+Contact: Mark Brown <broonie@opensource.wolfsonmicro.com>
+Description:
+ Some regulator directories will contain a field called
+ bypass. This indicates if the device is in bypass mode.
+
+ This will be one of the following strings:
+
+ 'enabled'
+ 'disabled'
+ 'unknown'
+
+ 'enabled' means the regulator is in bypass mode.
+
+ 'disabled' means that the regulator is regulating.
+
+ 'unknown' means software cannot determine the state, or
+ the reported state is invalid.
