From 03a0d1e81bdb519aa5881487cc5f20ffb8906c59 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 27 Nov 2012 16:41:16 +0200 Subject: OMAPDSS: DPI: remove omap_dss_device uses The role of struct omap_dss_device will change in the future. The exact details of that are still a bit unclear. However, the less uses of omap_dss_device we have, the easier the change is in the future. This patch removes uses of omap_dss_device from dpi.c, where it can be done neatly, by, for example, passing some lower level parameter in function parameters.
