Since the code being modified only exists on the fixes branch I've merged
this as a fix now.

I know this is more of a cleanup then a pure fix, but since the DMI quirks
always get updated through the fixes branch this avoids conflicts.

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Regards,

Hans
