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

Pull HID subsystem updates from Jiri Kosina:

 1) Support for HID over I2C bus has been added by Benjamin Tissoires.
    ACPI device discovery is still in the works.

 2) Support for Win8 Multitiouch protocol is being added, most work done
    by Benjamin Tissoires as well

 3) EIO/ERESTARTSYS is fixed in hiddev/hidraw, fixes by Andrew Duggan
    and Jiri Kosina

 4) ION iCade driver added by Bastien Nocera

 5) Support for a couple new Roccat devices has been added by Stefan
    Achatz

 6) HID sensor hubs are now auto-detected instead of having to list all
    the VID/PID combinations in the blacklist array

 7) other random fixes and support for new device IDs

EV_MSC events are used for input and output events that do not fall under other
categories.
A few EV_MSC codes have special meaning:
* MSC_TIMESTAMP:
- Used to report the number of microseconds since the last reset. This event
should be coded as an uint32 value, which is allowed to wrap around with
no special consequence. It is assumed that the time difference between two
consecutive events is reliable on a reasonable time scale (hours).
A reset to zero can happen, in which case the time since the last event is
unknown. If the device does not provide this information, the driver must
not provide it to user space.

EV_LED events are used for input and output to set and query the state of

---help---
Say Y here if you use a keyboard, a touchpad, a touchscreen, or any
other HID based devices which is connected to your computer via I2C.
If unsure, say N.
This support is also available as a module. If so, the module
will be called i2c-hid.
