[PATCH] fix pcmcia_request_irq() for multifunction card
multifunction cards need to have the same irq assigned to both functions. the code tries that but fails because ret is still set to CS_IN_USE which results in the function having the CB irq assigned. yenta_set_socket then just changes the irq routing to use the PCI interrupt but the first functions irq handler is registered on an ISA interrupt. boom.
