From 9f5e8f6efc7c2601136b27d9c7325c245f8fd19a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 22 Nov 2012 16:59:45 +0100 Subject: cfg80211: rework chandef checking and export it Some of the chandef checking that we do in cfg80211 to check if a channel is supported or not is also needed in mac80211, so rework that a bit and export the functions that are needed.
