This does look good at first glance. net-next is currently closed at
the moment, so this will have to be merged later.

At some point, we might also want to handle the mdio_bus irq array, as
that one is also usually dynamically allocated. Maybe we could just do
a static irq[PHY_MAX_ADDR] allocation, 32 times the size of an integer
might not be worth a potential leak.
