Subject[PATCH 4/4] media: mediatek: vcodec: dec: Set maximum resolution when S_FMT on output only
Date
Only the coded format impacts whether 4K resolution is supported: the
decoder does not support 4K for VP8, but does for other formats.

Update the maximum resolution in S_FMT only when called for the output
format. Otherwise we could set output format for VP8, then set capture
format, and then the resolution limit becomes inconsistent.

Fixes: b018be06f3c7 ("media: mediatek: vcodec: Read max resolution from dec_capability")
