[v3,6/6] drm/debugfs: Make the struct drm_debugfs_entry independent of DRM device

Commit Message

Maíra Canal Jan. 31, 2023, 7:58 p.m. UTC

In order to turn the API more expansible to other DRM objects, such as
the struct drm_connector, make the struct drm_debugfs_entry hold a void
pointer and cast the void pointer to the struct drm_device when needed.
