[PATCH 07/11] media: cedrus: Remove cedrus_codec enum

Jernej Skrabec
2022-10-24T22:03:47Z

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.
