Subject: [PATCH AUTOSEL 5.18 136/159] media: hantro: Stop using H.264 parameter pic_num

From: Nicolas Dufresne <nicolas.dufresne@...labora.com>

[ Upstream commit 831410700909f4e29d5af1ef26b8c59fc2d1988e ]

The hardware expects FrameNumWrap or long_term_frame_idx. Picture
numbers are per field, and are mostly used during the memory
management process, which is done in userland. This fixes two
ITU conformance tests:

  - MR6_BT_B
  - MR8_BT_B
