Hi Jacek and Arnd, Thanks for fixing this plus the ack! I chatted with Mauro, and as the patches are still only in mediatree, we'll apply this there, possibly with a minor spelling fix to the subject (depdendency -> dependency). <URL:https://git.linuxtv.org/sailus/media_tree.git/commit/?h=as3645a-fix2> Cc linux-media.
