[PATCH] fix pcmcia_request_irq() for multifunction card

Browse source 
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.
