Subject: cfg80211: Add stub for cfg80211_get_station()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=61aaa0e8c1c15d9e045f0577f046be50f2f571ab;p=linux-beck.git

cfg80211: Add stub for cfg80211_get_station()

This allows modules using this function (currently: batman-adv) to
compile even if cfg80211 is not built at all, thus relaxing
dependencies.
