linux-next: build warning after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (htmldocs)
produced this warning:

include/drm/drm_fb_helper.h:204: warning: Function parameter or member 'hint_leak_smem_start' not described in 'drm_fb_helper'

Introduced by commit

  e7c5c29a9eb1 ("drm/fb-helper: Set flag in struct drm_fb_helper for leaking physical addresses")
