Subject: [PATCH] atkbd - Fix Soltech TA12 volume hotkeys not sending key release

BugLink: https://bugs.launchpad.net//bugs/397499

Impact: Netbooks based on the Soltech TA12 do not send a key release
for volume keys causing Linux to think the key is constantly being
pressed forever.

Added quirk data for forced release keys.
