[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
