Subject: drm/amd/display: Temporary Disable MST DP Colorspace Property
From: Fangzhi Zuo <jerry.zuo@xxxxxxx>
commit 69a959610229ec31b534eaa5f6ec75965f321bed upstream.
Create MST colorsapce property for downstream device would trigger
warning message "RIP: 0010:drm_mode_object_add+0x8e/0xa0 [drm]"
After driver is loaded and drm device is registered, create
dp colorspace property triggers warning storm at
WARN_ON(!dev->driver->load && dev->registered && !obj_free_cb);
Temporary disabling MST dp colorspace property for now.
