X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=815ed41b9bd0ecbe9dbd58e594da94c2a35480d1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/omap: 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.
