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
