Updated comment style to kernel-doc format in drm_device.h
In struct drm_device there are 12 struct members without doc:
- registered
- filelist_mutex
- filelist
- irq
- vbl_lock
- event_lock
- hose
- sigdata
- sigdata.context
- sigdata.lock
- agp_buffer_map
- agp_buffer_token
They all need proper documentation, a task left for someone
that knows their usage.
drm_device is not plugged into Documentation/gpu/drm-internals.rst
as this would create a new load of warnings.
