[ Upstream commit 1f32061e843205f6fe8404d5100d5adcec334e75 ]
On a decoder instance, after the profile has been parsed from the stream __v4l2_ctrl_s_ctrl() is called to notify userspace about changes in the read-only profile control. This ends up calling back into the CODA driver where a missing check on the s_ctrl caused the profile information that has just been parsed from the stream to be overwritten with the default baseline profile.
Later on the driver fails to enable frame reordering, based on the wrong profile information.
Fixes: 347de126d1da (media: coda: add read-only h.264 decoder profile/level controls)
