I tried to build after applying your patch:
CC drivers/gpu/drm/msm/dp/dp_ctrl.o
drivers/gpu/drm/msm/dp/dp_ctrl.c: In function ‘dp_ctrl_use_fixed_nvid’:
drivers/gpu/drm/msm/dp/dp_ctrl.c:1429:11: error: too few arguments to

I had to add the extra parameter like this:

+++ b/drivers/gpu/drm/msm/dp/dp_ctrl.c
@@ -1420,16 +1420,14 @@ void dp_ctrl_host_deinit(struct dp_ctrl *dp_ctrl)

- edid_quirks = drm_dp_get_edid_quirks(ctrl->panel->edid);
/*

if (drm_dp_is_branch(dpcd))
- return (drm_dp_has_quirk(&ctrl->panel->desc, edid_quirks,
- DP_DPCD_QUIRK_CONSTANT_N));
+ return (drm_dp_has_quirk(&ctrl->panel->desc, 0,
+ DP_DPCD_QUIRK_CONSTANT_N));
return false;
}
and then it builds.
