From 220df83a5394fbf7c1486ba7848794b7b351d598 Mon Sep 17 00:00:00 2001 From: Steven Price Date: Thu, 27 Jun 2019 16:53:17 +0100 Subject: [PATCH] drm/gem: Rename drm_gem_dumb_map_offset() to drm_gem_map_offset() drm_gem_dumb_map_offset() is a useful helper for non-dumb clients, so rename it to remove the _dumb and add a comment that it can be used by shmem clients.
