Subject: [PATCH 06/11] media: cedrus: set codec ops immediately
Date:   Mon, 24 Oct 2022 22:15:10 +0200
Message-Id: <20221024201515.34129-7-jernej.skrabec@gmail.com>
In-Reply-To: <20221024201515.34129-1-jernej.skrabec@gmail.com>

We'll need codec ops soon after output format is set in following
commits. Let's move current codec setup to set output format callback.
While at it, let's remove one level of indirection by changing
current_codec to point to codec ops structure directly.
