NAME
__root_device_register - allocate and register a root device
SYNOPSIS
struct device * __root_device_register(const char * name, struct module * owner);
ARGUMENTS
name
root device name
owner
owner module of the root device, usually THIS_MODULE
DESCRIPTION
This function allocates a root device and registers it using device_register. In order to free the returned device, use
root_device_unregister.
Root devices are dummy devices which allow other devices to be grouped under /sys/devices. Use this function to allocate a root device and
then use it as the parent of any device which should appear under /sys/devices/{name}
The /sys/devices/{name} directory will also contain a 'module' symlink which points to the owner directory in sysfs.
Returns struct device pointer on success, or ERR_PTR on error.
NOTE
You probably want to use root_device_register.
