Since commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), drm_debugfs_create_files() never fails and should return void. Therefore, remove its use as the return value of debugfs_init() functions and have the functions return void. v2: convert intel_display_debugfs_register() stub to return void too.
