From 05ccf211efbb6c8b5da2b5fda4f9399a7bc0db2e Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sun, 2 Jul 2017 13:11:02 +0530 Subject: [PATCH] drm: ttm: virtio-gpu: dma-buf: Constify ttm_place structures. ttm_place are not supposed to change at runtime. All functions working with ttm_place provided by work with const ttm_place. So mark the non-const structs as const.
