__ROOT_DEVICE_REGIST(9) | Device drivers infrastructure | __ROOT_DEVICE_REGIST(9) |
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.
NOTE¶
You probably want to use root_device_register.
