Subject: [PATCH v2 27/29] vt8500lcdfb: use display information in info not in var for panning
Date: Tue, 14 Jun 2011 09:25:05 +0000 [thread overview]
Message-ID: <1308043507-11083-28-git-send-email-laurent.pinchart@ideasonboard.com> (raw)
We must not use any information in the passed var besides xoffset,
yoffset and vmode as otherwise applications might abuse it.
