264  * DOC: driver instance overview
266  * A device instance for a drm driver is represented by &struct drm_device. This
268  * bus-specific ->probe() callbacks implemented by the driver. The driver then
283  * any other resources allocated at device initialization and drop the driver's
288  * driver is unbound from the underlying physical struct &device. Best to use
296  * Display driver example
299  * The following example shows a typical structure of a DRM display driver.
388  *		.driver = {
399  * use drm_dev_unplug() instead of drm_dev_unregister(). The driver must protect
404  * paths are protected, they will not run on regular driver module unload,
575  *    should point at &struct drm_device of the device instance, not some driver
581  *    functions to find such components at driver load time, like
