Could you reword the commit message to explain the actual mechanism?
Something like:

On ASUS ROG Strix G16 G614 series laptops, the firmware leaves this
ActiveBoth GPIO line asserted (logic low) at boot. Per the boot-time
initial-state logic, an ActiveBoth interrupt found low is replayed
once to sync its initial state, which calls the handler synchronously
in the probe path. On these laptops that interrupt handler is slow/hanging,
so the synchronous call blocks for ~36 s and stalls boot.

It's also worth noting that commit 3bb62e3f99a5 already restricts the
boot-time replay to ActiveBoth interrupts that are asserted (low) — the pin
on ASUS ROG Strix G16 G614 series laptops meets exactly that condition,
which is why it still triggers. Disabling edge_events_on_boot via the
DMI quirk is therefore the right workaround for these laptops.

Thanks,
