From dcd215801b0279f0a021516526cf7c0b67d5302e Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 23 Feb 2017 16:05:38 +0800 Subject: [PATCH] drm/sun4i: Drop primary layer pointer from sun4i_drv The current layer init code keeps a pointer to the primary plane layer in sun4i_drv. When we eventually support multiple display pipelines, this would force us to keep track of primary planes for all crtcs. And these pointers only get used at bind time. Instead, have the crtc init code iterate through the returned layers to find the primary and cursor layers. And drop the pointer from the sun4i_drv structure.
