media: rc: sunxi-cir: Unregister rc device on probe failure
In the Linux kernel, the following vulnerability has been resolved: media: rc: sunxi-cir: Unregister rc device on probe failure After rc_register_device() succeeds, later probe failures must undo the registration with rc_unregister_device(). The current error path jumps to the allocation cleanup label and only calls rc_free_device(), leaving the rc device registration and resources created by rc_register_device() behind. Add a registered-device unwind label for the IRQ lookup, IRQ request, and hardware initialization failure paths. Keep rc_free_device() for failures before rc_register_device() succeeds.
