[ Upstream commit fd61d77a3d28444b2635f0c8b5a2ecd6a4d94026 ]
Static analyzers generate alerts for an unchecked call to `media_device_register()`. However, in this case, the device will work reliably without the media controller API.
Add a comment above the call to prevent future unnecessary changes.
