From 49a58f26af7b5ee28ea8788fcd2bb7b590c711c5 Mon Sep 17 00:00:00 2001 From: Liviu Dudau Date: Tue, 13 Jun 2017 12:18:03 +0100 Subject: [PATCH] drm/arm: hdlcd: Use CMA helper for plane buffer address calculation CMA has gained a recent helper function for calculating the start of the plane buffer's physical address. Use that instead of the hand rolled version.
