Subject: [PATCH v2 0/2] Add support for Lenovo Compact Keyboard

This patchset follows on from my previous attempt[1] to add support for
these keyboards from Lenovo.

Changes since v1:
* Merge driver into hid-lenovo-tpkbd.c instead of creating our own
  driver for the hardware [Jiri Kosina]
* Remove key mappings which are now supported by standard
* Use KEY_FILE for Fn-F12 (opens My Computer on Windows)
* Support the USB variant as well as Bluetooth
* Expose the Fn Lock setting as a sysfs attribute instead of trying to
  build a mechanism to toggle into the kernel

I got rid of the Fn-lock toggle code since it didn't play nicely with
the USB keyboard; from what I could ascertain, hid_output_raw_report
wants to sleep when sending a report to a USB keyboard, which isn't
allowed. The same was true when using an input handler.

A sysfs attribute is more flexible anyway, and one could trivially
script a user-space toggling mechanism around it. I suspect in
reality so long as Fn-Lock is left on nobody will really care what the
Fn-Lock key does :)

Applies and tested against 3.14.5.

Cheers,
