rio_dev_get - Increments the reference count of the RIO device structure

: RIO device being referenced

Each live reference to a device should be refcounted.

Drivers for RIO devices should normally record such references in their probe() methods, when they bind to a device, and release them by calling rio_dev_put(), in their disconnect() methods.

void rio_dev_put

(

struct rio_dev *

rdev

)

rio_dev_put - Release a use of the RIO device structure

: RIO device being disconnected

Must be called when a user of a device is finished with it. When the last user of the device calls this function, the memory of the device is freed.

Definition at line 74 of file rio-driver.c.

int rio_register_driver

(

struct rio_driver *

rdrv

)

rio_register_driver - register a new RIO driver : the RIO driver structure to register

Adds a &struct rio_driver to the list of registered drivers. Returns a negative value on error, otherwise 0. If no error occurred, the driver remains registered even if no device was claimed during registration.

Definition at line 143 of file rio-driver.c.

void rio_unregister_driver

(

struct rio_driver *

rdrv

)

rio_unregister_driver - unregister a RIO driver : the RIO driver structure to unregister

Deletes the &struct rio_driver from the list of registered RIO drivers, gives it a chance to clean up by calling its remove() function for each device it was responsible for, and marks those devices as driverless.
