Subject: drm/udl: dma-buf: Constify dma_buf_ops structures.
Git-commit: 7b4e1eaa9d9eb3662876833bafcbe059eb6ac186
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
dma_buf_ops are not supposed to change at runtime. All functions
working with dma_buf_ops provided by <linux/dma-buf.h> work with
const dma_buf_ops. So mark the non-const structs as const.
