Subject: media: cedrus: Set the platform driver data earlier
Author:  Dmitry Osipenko <dmitry.osipenko@collabora.com>
Date:    Thu Aug 18 22:33:07 2022 +0200

The cedrus_hw_resume() crashes with NULL deference on driver probe if
runtime PM is disabled because it uses platform data that hasn't been
set up yet. Fix this by setting the platform data earlier during probe.
