[PATCH] handle errors returned by platform_get_irq*()
platform_get_irq*() now returns on -ENXIO when the resource cannot be found. Ensure all users of platform_get_irq*() handle this error appropriately. Signed-off-by: David Vrabel <dvrabel@arcom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
