[PATCH v2 00/17] drm: subsytem-wide debugfs functions refactor

[Wambui Karuga]

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. 

v2: individual driver patches have been converted to have debugfs
functions return 0 instead of void to prevent breaking individual driver
builds.
The last patch then converts the .debugfs_hook() and its users across
all drivers to return void.

Wambui Karuga (17):
  drm/tegra: remove checks for debugfs functions return value
  drm/tilcdc: remove check for return value of debugfs functions.
  drm/v3d: make v3d_debugfs_init() return 0
  drm/vc4: remove check of return value of drm_debugfs functions
  drm/arc: make arcgpu_debugfs_init() return 0.
  drm/arm: make hdlcd_debugfs_init() return 0
  drm/etnaviv: remove check for return value of
    drm_debugfs_create_files()
  drm/msm: remove checks for return value of drm_debugfs_create_files()
  drm/sti: remove use of drm_debugfs functions as return values
  drm/vram-helper: make drm_vram_mm_debugfs_init() return 0
  drm/nouveau: make nouveau_drm_debugfs_init() return 0
  drm/pl111: make pl111_debugfs_init return 0
  drm/omap: remove checks for return value of drm_debugfs functions
  drm/i915: have *_debugfs_init() functions return void.
  drm: make various debugfs_init() functions return 0
  drm/debugfs: remove checks for return value of drm_debugfs functions.
  drm: convert .debugfs_init() hook to return void.
