From 031df82514b4a258ceee381fa19aa02a1188c470 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Tue, 25 May 2021 17:10:55 +0200 Subject: drm/ttm: Remove ttm_bo_mmap() and friends MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The function ttm_bo_mmap is unused. Remove it and it's helpers; including the verify_access callback in struct ttm_device_funcs.
