Huh, sorry, but why?

You might not know this, but Bagas is somebody that helps with
regression tracking (many thx for this BTW), so he's not even affected
by the problem -- and most likely is neither familiar with the code or
has the hardware to test the quirk entry.

Sure, asking others for help is fine. But from what I see this is
something that should be handled by those that developed the culprit.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
