Commit Message

Chen-Yu Tsai June 27, 2022, 11:24 a.m. UTC 
In commit b018be06f3c7 ("media: mediatek: vcodec: Read max resolution
from dec_capability") the driver ended up blindly setting the maximum
resolution to 1080p, even if the hardware and default output format
supported up to 4K. This would only be overridden by a subsequent
S_FMT call.

Correctly initialize the maximum resolution based on the default output
format.

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