From 355b3a982095c8647cce13dd43ebc4bc4299f31a Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Fri, 16 Nov 2012 18:23:36 +0530 Subject: [PATCH] ath6kl: Move and rename ath6kl_cleanup_vif function Rename ath6kl_cleanup_vif function as 'ath6kl_cfg80211_vif_stop' which is the more appropriate name considering the functionality of the module and vif specific cleanup is actually done by ath6kl_cfg80211_vif_cleanup. Also move it to cfg80211.c. Also make ath6kl_cfg80211_sta_bmiss_enhance as static function. This addresses a FIXME/TODO.
