Subject: media: ccs: Align flipping behaviour with other drivers
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Tue Mar 28 14:34:42 2023 +0300
No longer mirror flipping controls if the sensor is mounted upside down.
This way the behaviour of the flipping controls and rotation of the sensor
are aligned with the rest of the drivers.
