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.
