s390/pci: Implement IRQ functions if !PCI
All architectures must implement IRQ functions. Since various dependencies on !S390 were removed, there are various drivers that can be selected but will fail to link. Provide a dummy implementation of these functions for the !PCI case. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Cc: stable@vger.kernel.org # 3.9 Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
