CVE-2022-49129: mt76: mt7921: fix crash when startup fails.
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7921: fix crash when startup fails.
If the nic fails to start, it is possible that the resetwork has already been scheduled. Ensure the work item is canceled so we do not have use-after-free crash in case cleanup is called before the work item is executed.
This fixes crash on my x8664 apu2 when mt7921k radio fails to work. Radio still fails, but OS does not crash.
