From 48cf53f4343ae12ddc1c60dbe116161ecf7a2885 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Tue, 28 Jul 2015 17:53:23 +0900 Subject: [PATCH] drm/exynos: create a fake mmap offset with gem creation Don't create a fake mmap offset in exynos_drm_gem_dumb_map_offset. If not, it will call drm_gem_create_mmap_offset whenever user requests DRM_IOCTL_MODE_MAP_DUMB ioctl.
