[PATCH 6.1 191/609] media: cedrus: clean up media device on probe failure

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

------------------

From: Myeonghun Pak <[email protected]>

commit 2c869b6969f3061cbbdab587f4c0a88bd7fc3cc9 upstream.

cedrus_probe() initializes the media device before registering the video
device, the media controller, and the media device. If any of those later
steps fails, probe returns without calling media_device_cleanup(), so the
media device internals initialized by media_device_init() are left behind.

Add a media-device cleanup label to the probe unwind path and route video
registration failures through it as well.
