From 1c1c2b37325934b4318c46966feb03ad9fe83d8a Mon Sep 17 00:00:00 2001 From: Dmitry Antipov Date: Fri, 15 Dec 2023 15:38:51 +0300 Subject: wifi: cfg80211: introduce cfg80211_ssid_eq() Since SSIDs comparison is commonly used across many drivers, introduce generic 'cfg80211_ssid_eq()' to replace driver-private implementations.
