From 26eb994d52399a4767be30ccc2a7d68a0f34cadc Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sun, 18 Dec 2016 04:27:24 +0530 Subject: [PATCH] libertas: constify cfg80211_ops structures cfg80211_ops structures are only passed as an argument to the function wiphy_new. This argument is of type const, so cfg80211_ops strutures having this property can be declared as const.
