[RFC 3/5] drm/i915/dp: Remove redundant AUX backlight frequency calculations

2020-12-09 Thread Lyude Paul
Noticed this while moving all of the VESA backlight code in i915 over to DRM helpers: it would appear that we calculate the frequency value we want to write to DP_EDP_BACKLIGHT_FREQ_SET twice even though this value never actually changes during runtime. So, let's simplify things by just caching thi
