From 7b4e1eaa9d9eb3662876833bafcbe059eb6ac186 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sat, 1 Jul 2017 18:06:46 +0530 Subject: [PATCH] drm/udl: dma-buf: Constify dma_buf_ops structures. dma_buf_ops are not supposed to change at runtime. All functions working with dma_buf_ops provided by work with const dma_buf_ops. So mark the non-const structs as const.
