[PATCH] net: wireless: ath: wil6210: constify cfg80211_ops structures

From: Bhumika Goyal
Date: Sat Dec 17 2016 - 17:45:08 EST


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.
Done using Coccinelle
