On MT7915, MCU hangs do not trigger watchdog interrupts, so they can only

We applied this to our hacked upon 6.10 kernel, and this patch appears
to cause NPE down in debugfs file removal during radio restart. We didn't investigate this
closely, but removing this patch fixes the problem.
Also of note, we see the radio have a timeout, but then recover, often
(without this patch).
Did you force/fake this situation to happen and see it actually work?
I found some issues in a few patches of this series in the last few days
and will send v2 soon.
