This file details changes in 2.6 which affect PCMCIA card driver authors:
* Unify detach and REMOVAL event code, as well as attach and INSERTION
code (as of 2.6.16)
void (*remove) (struct pcmcia_device *dev);
int (*probe) (struct pcmcia_device *dev);
* Move suspend, resume and reset out of event handler (as of 2.6.16)
int (*suspend) (struct pcmcia_device *dev);
int (*resume) (struct pcmcia_device *dev);
should be initialized in struct pcmcia_driver, and handle
(SUSPEND == RESET_PHYSICAL) and (RESUME == CARD_RESET) events
* event handler initialization in struct pcmcia_driver (as of 2.6.13)
The event handler is notified of all events, and must be initialized
as the event() callback in the driver's struct pcmcia_driver.
