Subject: [PATCH] net: wireless: ath: wil6210: constify cfg80211_ops structures
Date: Sun, 18 Dec 2016 04:14:27 +0530 [thread overview]
Message-ID: <1482014667-27082-1-git-send-email-bhumirks@gmail.com> (raw)
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
