Pull input layer fixes from Dmitry Torokhov:
 "Second round of updates for the input subsystem.  Mostly small fixups
  to the code merged in the first round (atmel_mxt_ts, wacom) but also a
  smallish patch to xbox driver to support Xbox One controllers and a
  patch to better handle Synaptics profile sensors found in Cr-48
  Chromebooks that should not affect any other devices"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: edt-ft5x06 - remove superfluous assignment
  Input: xpad - add support for Xbox One controllers
  Input: atmel_mxt_ts - fix a few issues reported by Coverity
  Input: atmel_mxt_ts - split config update a bit
  Input: atmel_mxt_ts - simplify mxt_initialize a bit
  Input: joystick - use get_cycles on ARMv8
  Input: wacom - fix compiler warning if !CONFIG_PM
  Input: cap1106 - allow changing key mapping from userspace
  Input: synaptics - use firmware data for Cr-48
  Input: synaptics - properly initialize slots for semi-MT
  Input: MT - make slot cleanup callable outside mt_sync_frame()
  Input: atmel_mxt_ts - mXT224 DMA quirk was fixed in firmware v2.0.AA

Prepare second round of input updates for 3.17.

Somehow we ended up with a duplicate line in edt_ft5x06_register_write()

Xbox One controllers require an initialization message to start sending
data, so xpad_init_output becomes a required function. The Xbox One
controller does not have LEDs like the Xbox 360 controller, so that
functionality is not implemented. The format of messages controlling rumble
is currently undocumented, so rumble support is not yet implemented.

Note that Xbox One controller advertises three interfaces with the same
interface class, subclass and protocol, so we have to also match against
interface number.

Let's split config update code a bit so it is hopefully a bit easier to
read. Also, the firmware update callback should be the entity releasing
firmware blob, not lower layers.

I think having control flow with 2 goto/labels/flags is quite hard to read,
this version is a bit more readable IMO.

As with ARM the ARMv8 architecture provides a cycle counter which can be
used to provide a high resolution time for the joystick driver and
silence the build warning that results from not having a precise timer
on ARMv8, making allmodconfig and allyesconfig quieter.
