From 8b6fe20a5d7bc467865adb08c5abcf9e712cdc39 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sat, 21 Jan 2017 07:37:25 -0200 Subject: [PATCH] [media] media: pci: constify vb2_ops structure Declare vb2_ops structure as const as it is only stored in the ops field of a vb2_queue structure. This field is of type const, so vb2_ops structures having same properties can be made const too.
