Date: Sun, 2 Jul 2017 11:49:40 +0530 From: Arvind Yadav <arvind.yadav.cs@...il.com> To: tomi.valkeinen@...com, airlied@...ux.ie Cc: dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org Subject: [PATCH] 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 <linux/dma-buf.h> work with const dma_buf_ops. So mark the non-const structs as const.
