From: hersen wu <[email protected]> [Why] amdgpu_dm->backlight_caps is for single eDP only. the caps are upddated for very connector. Real eDP caps will be overwritten by other external display. For OLED panel, caps->aux_support is set to 1 for OLED pnael. after external connected, caps+.aux_support is set to 0. This causes OLED backlight adjustment not work.
[How] within update_conector_ext_caps, backlight caps will be updated only for eDP connector.
