For this series, we do some clean-up and fix a build warning.
This series is based on linux-next-20220914.

It is more clear to modify this in mtk_dp_bdg_detect().

Some definitions in mtk_dp_reg.h are not used, so remove these
redundant codes.

I agree with this commit. Since you anyway have to send a v2 of this series,
please clarify the commit description and title, something like:
drm/mediatek: dp: Reduce indentation in mtk_dp_bdg_detect()
In order to improve human readability, reduce the indentation by returning
early if the dp/edp cable is not plugged in.
Cheers,
Angelo
