## Description

In the Linux kernel, the following vulnerability has been resolved:  wifi: mt76: mt7925: cancel mlo_pm_work on stop  mt7925 queues mlo_pm_work with a 5 second delay during multi-link power-save setup and never cancels it on the stop path. If the device is torn down inside that window, the work outlives the teardown and its timer fires afterwards, trying to queue onto the workqueue that is already gone:    workqueue: cannot queue mt7925_mlo_pm_work [mt7925_common] on wq phy0   WARNING: kernel/workqueue.c:2283 at __queue_work+0x59/0xa0, CPU#1: swapper/1/0    call_timer_fn+0x2a/0x140    __run_timers+0x203/0x330    run_timer_softirq+0x86/0xf0  mt7921 already has its own stop callback, so add one for mt7925 that cancels the work before calling mt792x_stop(). mt7925_ops backs both the PCIe and USB drivers, so this covers both.
