provide probe() and remove() methods. They support power management
and shutdown notifications using the standard conventions::
struct platform_driver {
int (*probe)(struct platform_device *);
- int (*remove)(struct platform_device *);
+ void (*remove)(struct platform_device *);
void (*shutdown)(struct platform_device *);
int (*suspend)(struct platform_device *, pm_message_t state);

int (*resume)(struct platform_device *);
struct device_driver driver;
+ const struct platform_device_id *id_table;
+ bool prevent_deferred_probe;
+ bool driver_managed_dma;
};
Note that probe() should in general verify that the specified device hardware
actually exists; sometimes platform setup code can't be sure. The probing
can use device resources, including clocks, and device platform_data.
