Description
Description
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.
