drm/fbdev-helper: Grab mode_config.mutex in drm_fb_helper_single_add_all_connectors
This is now truly only duct-tape to keep locking checks happy since calling this function when hpd or polling are already enabled is a bug. The fbdev helper can't cope with hotplug changes yet at this point, only after that. Otoh a bit more robustness in this function can't hurt, and with this fbdev can actually cope with hotplug changes. And it's also more consistent with the connector hotadd/remove dp mst needs to do. Therefore document this as new official behavior. Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
