From 6e03db38631f5607e81856418ffe779c29e53c56 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sat, 1 Jul 2017 07:27:13 -0400 Subject: [PATCH] media: vb2 dma-contig: 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.
