This series includes work on various debugfs functions both in drm/core
and across various drivers in the subsystem.
Since commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files()
never fail), drm_debugfs_create_files() does not fail and only returns
zero. This series therefore removes the left over error handling and
checks for its return value across drm drivers.

As a result of these changes, most drm_debugfs functions are converted
to return void in this series. This also enables the
drm_driver,debugfs_init() hook to be changed to return void. 

Wambui Karuga (21):
  drm/debugfs: remove checks for return value of drm_debugfs functions.
  drm: convert the drm_driver.debugfs_init() hook to return void.
  drm: convert drm_debugfs functions to return void
  drm/vram-helper: make drm_vram_mm_debugfs_init() return void
  drm/vc4: remove check of return value of drm_debugfs functions
  drm/arc: make arcpgu_debugfs_init return void
