Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.
