6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: David (Ming Qiang) Wu <David.Wu3@xxxxxxx>
commit 8409fb50ce48d66cf9dc5391f03f05c56c430605 upstream.
Similar to jpeg_v2_dec_ring_parse_cs() but it has different
register ranges and a few other registers access.
