Comment 84 for bug 271706

Nick Moeck: your patch is invalid. You need to edit the @ modified section delimiters to have a valid patch.

Aryeh Gregor: I tried applying your patch on linux-image 2.6.31-17-generic but it does not apply: 'atkbd_volume_forced_release_keys' is not in standard kernel. I've fixed it and you will find the 'generic' patch attached.

Nevertheless it does not fix the problem. See the following evtest output:

First is 'Space' keypress and release. The second is turning the wheel one notch Up.
a) the event is repeated 3 times - looks like the anti-repeat in drivers/input/keyboard/atkbd.c:482 does not work in this case
b) even with atkbd_setup_forced_release quirk the sequence is wrong - this is why I posted Space keypress for reference
VolumeUp key is depressed (0) then pressed (1) three times
This leaves the button in pressed state, causing the "sticking" behavior.
