From: "Carlos E.C. Barbosa" <carlosecb@xxxxxxxxxxxx> There is overlapping code over two distinct lists. This repurposes vimc_pix_map for mapping formats and remaps the calls to the matching v4l2_format_info. --- Changes in v2: As advised by Helen Koike and Hans Verkuil, the const qualifiers are not removed, the bayer flag is kept and the unnecessary changes are not made. Changes in v3: Change declaration order of variables and some minor style changes. v4l2-compliance message: https://pastebin.com/UkmfjuLa Signed-off-by: Carlos E. C.
