[PATCH v4,1/6] media: mtk-vcodec: venc: remove redundant code

From: Irui Wang
Date: Fri May 21 2021 - 03:02:04 EST


From: Alexandre Courbot <acourbot@xxxxxxxxxxxx>

vidioc_try_fmt() does clamp height and width when called on the OUTPUT
queue, so clamping them prior to calling this function is redundant. Set
the queue's parameters after calling vidioc_try_fmt() so we can use the
values it computed.
