Subject: [PATCH 1/7] drm: extract drm_kms_helper_hotplug_event
Date: Tue, 23 Oct 2012 20:23:32 +0200	[thread overview]
Message-ID: <1351016618-2752-2-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1351016618-2752-1-git-send-email-daniel.vetter@ffwll.ch>

Useful if drivers want to be slightly more clever about hotplug
handling.
