[PATCH 5.1 76/96] drm/virtio: move drm_connector_update_edid_property() call

[Greg Kroah-Hartman]

From: Gerd Hoffmann <kraxel@xxxxxxxxxx>

commit 41de4be6f6efa4132b29af51158cd672d93f2543 upstream.

drm_connector_update_edid_property can sleep, we must not
call it while holding a spinlock.  Move the callsite.
