Subject: input: fix HP 2133 not sending release event for video switch
From: Jiri Kosina <jkosina@xxxxxxx>
Video switch key on HP 2133 doesn't send release event, so we have to
create workaround similar to what we do for Dell Latitude, i.e. perform
DMI match for the system and generate 'false' release event ourselves, so
that userspace doesn't think that the key is stuck forever.
