[PATCH 6/7] drm/i915/display: convert dp aux backlight to struct intel_display

Jani Nikula jani.nikula at intel.com
Tue Aug 13 16:41:22 UTC 2024


Going forward, struct intel_display shall replace struct
drm_i915_private as the main display device data pointer type. Convert
intel_dp_aux_backlight.[ch] to struct intel_display.
