Subject: media: cedrus: Properly signal size in mode register
Author: Jernej Skrabec <jernej.skra...@siol.net>
Date: Sun Nov 10 07:30:01 2019 +0100
Mode register also holds information if video width is bigger than 2048
and if it is equal to 4096.
Rework cedrus_engine_enable() to properly signal this properties.
