Felix Fietkau 5ea8b6187d mt76: mt76x02: clean up and fix interrupt masking in the irq handler
Only clear unmasked interrupts. If an interrupt is temporarily masked,
its pending events need to be processed later, even if another interrupt
happened in the mean time.
Disable interrupts in one call before scheduling

Dan CarpenterandFelix Fietkau 379445b4aa mt76: mt7915: potential array overflow in mt7915_mcu_tx_rate_report()
Smatch complains that "wcidx" value comes from the network and thus
cannot be trusted.  In this case, it actually seems to come from the
firmware.  If your wireless firmware is malicious then probably no
amount of carefulness can protect you.

On the other hand, these days we still try to check the firmware as much
as possible.  Verifying that the index is within bounds will silence a
static checker warning.  And it's harmless and a good exercise in kernel
hardening.  So I suggest that we do add a bounds check.
