Subject: [RFC v4 05/25] drm/fb-helper: dpms_legacy(): Only set on connectors in use
Date: Sat, 14 Apr 2018 13:52:58 +0200	[thread overview]
Message-ID: <20180414115318.14500-6-noralf@tronnes.org> (raw)
In-Reply-To: <20180414115318.14500-1-noralf@tronnes.org>

For each enabled crtc the functions sets dpms on all registered connectors.
Limit this to only doing it once and on the connectors actually in use.
