This unconditionally says it handled an interrupt regardless of what
happened. This means that the interrupt line can't be shared and that
the error handling code in the generic interrupt subsystem can't tell if
something goes wrong and the interrupt gets stuck.

Are you sure the interrupt handler can safely use managed resources,
especially given...

...that things like the register map and the I/O resources for the chip
are allocated after and therefore freed before before the interrupt is
freed. Normally the interrupt should be one of the last things to be
allocated.

In general if functions can legitimately be empty they should just be
omitted, if they are required that usually means they have to do
something.
