I *looked* at that ordering and then went "Naah, that makes no sense".
But if that's the only issue, how about we just re-order those things
- we still don't need to move the irq_request_resources() into the
spinlock, we just move it to below the chip_bus_lock().
IOW, something like the (COMPLETELY UNTEESTED!) attached patch.
This assumes that the chip_bus_lock() thing is still ok for the RT
case, but it looks like it might be: the only other one I looked at
(apart from the gpio-omap one) used a mutex.
