drv
probe
Use this instead of platform_driver_register when you know the device is not hotpluggable and has already been registered, and you want to remove its run-once probe infrastructure from memory after the driver has bound to the device.
One typical use for this would be with drivers for controllers integrated into system-on-chip processors, where the controller devices have been configured as part of board setup.
Returns zero if the driver registered and bound to a device, else returns a negative error code and with the driver not registered.
