From 169faecadd2444fc295c724c0a2f622b99e6bf19 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 9 Jul 2015 23:44:27 +0200 Subject: [PATCH] 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 Signed-off-by: Daniel Vetter --- Reading git-format-patch failed
