Subject: [PATCH] drm/i915/display: Suspend MST topology manager before destroy fbdev
Date: Tue, 26 Nov 2019 18:16:09 -0800	[thread overview]
Message-ID: <20191127021609.162700-1-jose.souza@intel.com> (raw)

MST do topology probe in threads, so this running threads needs to be
flushed before fbdev is destroyed as when a new MST node is found it
calls drm_kms_helper_hotplug_event() that calls fbdev functions
