You shouldn't need this any more; the driver used to be faffing around
with this because it wasn't using genirq for this in the past.

Simiarly here as far as I know; the original code predates genirq
support for this so is doing some hairy stuff that is no longer
required and may actually be harmful.

What I'd expect to see from a conversion like this would be that most of
the locking/IRQ management stuff would be dropped and the bus_lock() and
bus_sync_unlock() operations would be implemented.
