DEVICE_ADD(9) Device drivers infrastructure DEVICE_ADD(9)
NAME device_add - add device to device hierarchy.
SYNOPSIS int device_add(struct device * dev);
ARGUMENTS dev device.
DESCRIPTION This is part 2 of device_register, though may be called separately _iff_ device_initialize has been called separately.
This adds dev to the kobject hierarchy via kobject_add, adds it to the global and sibling lists for the device, then adds it to the other relevant subsystems of the driver model.
NOTE _Never_ directly free dev after calling this function, even if it returned an error! Always use put_device to give up your reference instead.
