If anyone has any objections, please let me know. ------------------ From: Satyajit Roy [ Upstream commit bdcd0411d7d186225a52458fd42bb70d54ca917a ] DC uses dc_edid_caps.qs_bit when constructing the HDMI AVI InfoFrame quantization-range field. Although DRM parses the sink capability into drm_display_info, DM never copies it into the DC EDID capabilities. The field therefore remains zero and the AVI quantization range stays at its default value. Copy rgb_quant_range_selectable for HDMI sinks and extend the existing EDID-capability KUnit test to cover it.
