Re: [PATCH] drm/mediatek: cleanup coding style in mediatek a bit

Hi, Bernard:

Bernard Zhao bernard@vivo.com 於 2020年4月27日 週一 下午3:53寫道：

This code change is to make code bit more readable. Optimise array size align to HDMI macro define. Add check if len is overange.

One patch should just do one thing, but this do three things. So break this into three patches.

Regards, Chun-Kuang.
