SRU Justification:

Impact:
  Some hotkeys do not produce key release events so not function well.

Fix:
  Add quirks in atkbd.c to force a key release.
  (in 2.6.32, this can be done via /sys from userspace)

Testcase:
  A user reported this patch works well.

Subject: [PATCH] UBUNTU: SAUCE: (drop after 2.6.31) input: Add hotkey quirk for Samsung Q210/P210 laptops

Hotkeys do not produce release events. Add the quirk to force a key release.

In 2.6.32, a /sys interface is provided to handle setting from userspace.
It is not necessary to apply this patch to newer version than 2.6.31.
