Not sure what the full merge pipeline is here, but my original patch
was not sent to the stable mailing list. So I would assume that it
went through the normal release gates / checks ? If there was a fault
on the way I uploaded the patches I do apologise however I did follow
the normal guidelines as far as I understood them.

Personally I did validate this patch on systems with Intel and AMD GFX,
unfortunately I do not have any ARM based dev kits that are able to run
mainline (was never able to get an Nvidia TK1 to boot outside of L4T)
