From 9a9f5ce8db176499a7f3f93172bf34176aa460f5 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 9 Jul 2015 23:44:34 +0200 Subject: drm: Roll out drm_for_each_connector more Now that we also grab the connection_mutex and so fixed the race with atomic modeset we can use the iterator there too. The other special case is drm_connector_unplug_all which would have a locking inversion with the sysfs store/show functions if we'd grab the mode_config.mutex around the unplug. We could just grab connection_mutex instead, but that's a bit too much a dirty trick for my taste. Also it's only used by udl, which doesn't do any other kind of connector hotplugging, so should be race-free. Hence just stick with a comment for now.
