Subject: [PATCH 07/11] media: cedrus: Remove cedrus_codec enum
Date:   Mon, 24 Oct 2022 22:15:11 +0200
Message-Id: <20221024201515.34129-8-jernej.skrabec@gmail.com>
In-Reply-To: <20221024201515.34129-1-jernej.skrabec@gmail.com>
References: <20221024201515.34129-1-jernej.skrabec@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Last user of cedrus_codec enum is cedrus_engine_enable() but this
argument is completely redundant. Same information can be obtained via
source pixel format. Let's remove this argument and enum.

No functional changes intended.
