Subject: [PATCH] drm/nouveau: remove checks for return value of debugfs functions
Date:   Tue, 18 Feb 2020 20:28:17 +0300

As there is no need to check for the return value of debugfs_create_file
and drm_debugfs_create_files, remove unnecessary checks and error
handling in nouveau_drm_debugfs_init.
