This is not needed, really, if you have unique / distinguishable
messages in the first place.
Rather people include module names, which may be useful.
Makes sense, I'll switch to KBUILD_MODNAME.

GENMASK(4,0)
It's not really a register bitmask, but rather extracting the low bits
of an index... but sure, GENMASK also expresses that. Changed.

Isn't it easier to handle these when they are full width, i.e. 32
items per the array?
I don't think so, it doesn't really buy us anything. It's just a maximum
beyond which the driver doesn't work in its current state anyway (if the
number were much larger it'd make sense to dynamically allocate these,
but not at this point).

Good catch, but this is actually obsolete. Higher IRQs go into the FIQ
irqchip, so this should never happen (it's a leftover from when they
were a single one). I'll remove it.
Ack on the other comments, thanks!
