[PATCH 2/4] media: mediatek: vcodec: dec: Set default max resolution based on format

From: Chen-Yu Tsai
Date: Mon Jun 27 2022 - 07:25:44 EST


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.
