From ba527c13644fdeacdb4756fc9dd9aa598a40bce3 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 9 May 2017 01:27:12 +0300 Subject: [PATCH] drm: omapdrm: Store the Z order in the plane state zpos field The DRM core implements a standard "zpos" property to control planes ordering. The omapdrm driver implements a similar property named "zorder". Although we can't switch to DRM core handling of the "zpos" property for backward compatibility reasons, we can store the zorder value in the drm_plane_state zpos field, saving us from adding a custom field to the plane state.
