From: James Cowgill Date: Wed, 4 Jun 2025 14:38:48 +0000 (+0000) Subject: media: v4l2-ctrls: Fix H264 SEPARATE_COLOUR_PLANE check X-Git-Tag: v6.12.42~207 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1ff541ea9e0c33ff7c9e64a7698ffd8eeb398793;p=thirdparty%2Fkernel%2Fstable.git media: v4l2-ctrls: Fix H264 SEPARATE_COLOUR_PLANE check [ Upstream commit 803b9eabc649c778986449eb0596e5ffeb7a8aed ] The `separate_colour_plane_flag` element is only present in the SPS if `chroma_format_idc == 3`, so the corresponding flag should be disabled whenever that is not the case and not just on profiles where `chroma_format_idc` is not present.
