Subject: [PATCH v4 0/2] media: verisilicon: HEVC: fix 10bits handling

When decoding a 10bits bitstreams HEVC driver should only expose 10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
and to only change driver internal state in case of success.

Fluster score (140/147) doesn't change after this series.

version 4:
- Split the change in 2 patches.
- Change hantro_check_depth_match() prototype to avoid using
  ctx->bit_depth
- Return the result of hantro_reset_raw_fmt() to the caller.
- Only set ctx->bit_depth when hantro_reset_raw_fmt() returns is ok.

Benjamin Gaignard (2):
  media: verisilicon: Do not change context bit depth before validating
    the format
  media: verisilicon: HEVC: Only propose 10 bits compatible pixels
    formats
