Adam,

You don't really explain what the problem actually is. Can you elaborate ?

Also, I have been using platform_get_irq() to get the interrupt resource
in mfd client drivers and similar situations. Wouldn't this work here as well
if you don't want to use platform_get_irq_byname() ?

Thanks,
Guenter
