DEVICE_REGISTER(9) Device drivers infrastructure DEVICE_REGISTER(9)NAME
device_register - register a device with the system.
SYNOPSIS
int device_register(struct device * dev);
ARGUMENTS
dev
pointer to the device structure
DESCRIPTION
This happens in two clean steps - initialize the device and add it to
the system. The two steps can be called separately, but this is the
easiest and most common. I.e. you should only call the two helpers
separately if have a clearly defined need to use and refcount the
device before it is added to the hierarchy.
NOTE
_Never_ directly free dev after calling this function, even if it
returned an error! Always use put_device to give up the reference
initialized in this function instead.
