Hi all,

After merging the drm-intel tree, today's linux-next build (htmldocs)
produced these warnings:

drivers/gpu/drm/i915/display/intel_dsb.c:201: warning: Excess function 
parameter 'crtc_state' description in 'intel_dsb_reg_write'
drivers/gpu/drm/i915/display/intel_dsb.c:201: warning: Function parameter or 
member 'dsb' not described in 'intel_dsb_reg_write'
