Commit 6335e4d56681f6f08f24f4b812a72d402793d393 added hotkey support, but
fails to support the multimedia keys on some Toshiba laptops as they don't
generate key release events.
This was previously discussed in http://lkml.org/lkml/2009/4/11/139 and a
solution was found in private mail. The solution is to act on key press
events instead of on key release events.
Also remove one level of indentation.
