Series mtk-vcodec: venc: support for MT8183 and v4l2-compliance fixes | expand

Commit Message

Alexandre Courbot July 13, 2020, 6:08 a.m. UTC 
The time per frame was left initialized to 0/0, which make the driver
fail v4l2-compliance, and also leaves it potentially exposed to doing a
division by zero.
