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

Pull HID subsystem updates from Jiri Kosina:

 - The need for HID_QUIRK_NO_INIT_REPORTS per-device quirk has been
   growing dramatically during past years, so the time has come to
   switch over the default, and perform the pro-active reading only in
   cases where it's really needed (multitouch, wacom).

   The only place where this behavior is (in some form) preserved is
   hiddev so that we don't introduce userspace-visible change of
   behavior.

   From Benjamin Tissoires

 - HID++ support for power_supply / baterry reporting.

   From Benjamin Tissoires and Bastien Nocera

 - Vast improvements / rework of DS3 and DS4 in Sony driver.

   From Roderick Colenbrander

 - Improvment (in terms of getting closer to the Microsoft's
   interpretation of slightly ambiguous specification) of logical range
   interpretation in case null-state is set in the rdesc.

   From Valtteri Heikkilä and Tomasz Kramkowski

 - A lot of newly supported device IDs and small assorted fixes
