Subject: [PATCH] drm: Drop mode_config.mutex from get_resources ioctl
Date: Tue, 21 Jun 2016 14:41:08 +0200 [thread overview]
Message-ID: <1466512868-9182-1-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20160621094417.GD1821@nuc-i3427.alporthouse.com>
The only thing this protected is the connector_list, which is
now protected differently.
v2: Also remove comment (Chris).
