From 10eeb5e645b5332b24986a554046f6c9cc2c22d4 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sat, 21 Jan 2017 12:28:58 +0530 Subject: [PATCH] net: xilinx: constify net_device_ops structure Declare net_device_ops structure as const as it is only stored in the netdev_ops field of a net_device structure. This field is of type const, so net_device_ops structures having same properties can be made const too.
