X-Git-Tag: v4.14-rc1~67^2~13^2~4 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=53e3ca5cee24f5fafe4e9ff5fe4b230e1a1b85ed;p=platform%2Fkernel%2Flinux-rpi.git 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 work with const dma_buf_ops. So mark the non-const structs as const.
