tee: tee_shm: Constify dma_buf_ops structures.
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. File size before: text data bss dec hex filename 2026 112 0 2138 85a drivers/tee/tee_shm.o File size After adding 'const': text data bss dec hex filename 2138 0 0 2138 85a drivers/tee/tee_shm.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Jens Wiklander <jens.wiklander@linaro.org>
