[PATCH v2 0/2] Fix warnings with recent smatch

Posted by Ricardo Ribalda 1 week, 3 days ago

Recent versions of smatch preserve the address space qualifiers while
running typeof() [1]. This has triggered tens of new sparse warnings in
media-ci.

This series takes care of them following Dan's suggestion [2].
