[PATCH 19/19] drm/i915: Remove i915_debugfs_unregister()

Thu Jan 26 22:56:21 UTC 2017
drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so no need to do this explicitly. Additionally it
uses debugfs_remove_recursive() to clean up the debugfs files,
so no need for adding fake drm_info_node entries.
