From c2b13452b283f9c4a5b02a6b53ed6416ebf4c03c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 11 Sep 2008 00:01:55 +0200 Subject: mac80211: clean up scan namespace Most of the scan functions are called ieee80211_sta_scan_* or similar, make clean it up so they are all just called ieee80211_scan_*.
