Subject: [PATCH v2 0/2] Fix warnings with recent smatch
Date: Mon, 14 Sep 2026 13:53:30 +0000	[thread overview]
Message-ID: <20260914-unqual-v2-0-60a1407a0cd4@chromium.org> (raw)

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].
