Ok, good to know, thanks for your quick reply. I checked the commit
that caused the
warning, d2fe28feaebb ("[media] coda/imx-vdoa: constify structs"), and
it is currently
part of git://linuxtv.org/media_tree.git#master . My fix should go on
top of this branch
and picked up by whoever is going to send it during the merge window.
As I'm reverting
half of Mauro's patch, we can't merge it through any other tree at the moment.
