From 64cb81797f8b56e1806d67024de561b60944d1a5 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 13 Feb 2018 14:00:39 +0200 Subject: [PATCH] drm: omapdrm: dss: Pass omap_drm_private pointer to dss_mgr_ops The dss_mgr_ops operations implemented by the omapdrm side have to look up the omap_crtc objects from global variables as they are only passed a channel number. In order to remove global variables in the omapdrm driver pass the omap_drm_private pointer to the dss_mgr_ops. This requires storing a pointer to the omap_drm_private in a global variable on the DSS side as a temporary measure until the omapdrm and omapdss drivers get merged.
