5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 69080ec3d0daba8a894025476c98ab16b5a505a4 ]
A call to media_device_init() requires media_device_cleanup() counterpart to complete cleanup and release any allocated resources.
This has been done in the driver .remove() right from the beginning, but error paths on .probe() shall also be fixed.
