From 7ab3fdde04218c4733e96712b651751c413d51c3 Mon Sep 17 00:00:00 2001 From: "Jerry (Fangzhi) Zuo" Date: Tue, 17 Apr 2018 13:49:48 -0400 Subject: [PATCH] drm/amd/display: Update MST edid property every time Extended fix to: "Don't read EDID in atomic_check" Fix display property not observed in GUI display after hot plug. Call drm_mode_connector_update_edid_property every time in .get_modes hook, due to the fact that edid property is getting removed from usermode ioctl DRM_IOCTL_MODE_GETCONNECTOR each time in hot unplug.
