| 3 | Instead of the old pcmcia_request_irq() interface, drivers may now | ||
| 4 | choose between: | ||
| 5 | - calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq. | ||
| 6 | - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will | ||
| 7 | clean up automatically on calls to pcmcia_disable_device() or | ||
| 8 | device ejection. | ||
| 9 | - drivers still not capable of IRQF_SHARED (or not telling us so) may | ||
| 10 | use the deprecated pcmcia_request_exclusive_irq() for the time | ||
