In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix memory leak in ath12k_qmi_driver_event_work()
Currently the buffer pointed by event is not freed in case
ATH12K_FLAG_UNREGISTERING bit is set, this causes memory leak.
Add a goto skip instead of return, to ensure event and all the
list entries are freed properly.
