Before pushing I double checked my work and I noticed that this patch is wrong there is a subtle but important difference between intel_panel_actually_set_backlight() and intel_backlight_set_pwm_level() intel_panel_actually_set_backlight() calls: panel->backlight.funcs->set(conn_state, level); where as intel_backlight_set_pwm_level() calls: panel->backlight.pwm_funcs->set(conn_state, level); I missed the pwm_funcs vs funcs difference, the funcs->set function is normally just a wrapper for pwm_funcs->set, but the dp_aux and dsi_dsc code my overwrite the functions to which backlight.funcs point to so the difference matters. Tl;DR: self nack for this one. Patch 2/2 is still valid and I will push that out shortly.
