In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7921s: fix potential hung tasks during chip recovery

During chip recovery (e.g. chip reset), there is a possible situation that kernel worker reset_work is holding the lock and waiting for kernel thread stat_worker to be parked, while stat_worker is waiting for the release of the same lock. It causes a deadlock resulting in the dumping of hung tasks messages and possible rebooting of the device.

This patch prevents the execution of stat_worker during the chip recovery.
