Since 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 i915_debugfs_register() and
intel_display_debugfs_register() and have both functions return void.

You don't actually change the return type.

Otherwise, LGTM.
