Subject[PATCH 09/21] drm/nouveau: remove checks for return value of debugfs functions
Date
Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), there is no need to ever check
for the the return value of debugfs_create_file() and
drm_debugfs_create_files(). Therefore, remove unnecessary checks and
error handling in nouveau_drm_debugfs_init.

These changes also enable nouveau_drm_debugfs_init() to be declared
as void.
