The MPEG-4 decoder firmware reports profile and level indication values that can be used to update V4L2 MPEG-4 profile and level controls. Signed-off-by: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> --- Changes since v1 [1]: - Fix coda_decode_ctrls trying to set mpeg2_level_ctrl read-only, that should be mpeg4_level_ctrl.
