From 778014f0c80815e5e1ff079343da9673cb4db1a4 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Wed, 22 Jul 2015 14:58:08 +0530 Subject: [PATCH] drm/msm: Use new drm_fb_helper functions Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation.
