[Intel-gfx] ✗ warning: Fi.CI.BAT

Hi,
I got this message in reply to this patch (https://patchwork.freedesktop.org/patch/60736/).
It looks like most of the warnings are related to 'PWM1 enabled' warnings that happen when the hardware is going into some power management state and BLM_PWM_ENABLE and/or BLM_PCH_PWM_ENABLE are enabled on the bdw-ultra platform.
What is the best way to fix this? If my patch is used then the function that disables BLM_PWM_ENABLE and/or BLM_PCH_PWM_ENABLE (lpt_disable_backlight) will not be called.
Should I disable this DPCD backlight control featured for BDW or specifically disable these bits in my intel_dp_aux_enable_backlight function?
Thank you.
Yetunde
