Subject: [PATCH v2 5/7] media: mtk-vcodec: replace func vidioc_try_fmt with two funcs for out/cap
Date: Wed, 17 Nov 2021 15:06:33 +0200	[thread overview]
Message-ID: <20211117130635.11633-6-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20211117130635.11633-1-dafna.hirschfeld@collabora.com>

The function vidioc_try_fmt has a big 'if-else' for
the capture and output cases. There is hardly any code
outside of that condition. It is therefore better to split
that functions into two different functions, one for each case.
