6.5-stable review patch. If anyone has any objections, please let me know. ------------------ 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.
