+commit edcdf0989410a05a6a4b8438df4010447eaa7d9a
+Author: Felix Fietkau <nbd@openwrt.org>
+Date: Sun Jun 22 13:36:20 2014 +0200
+
+ Revert "cfg80211: Use 5MHz bandwidth by default when checking usable channels"
+
+ It enables channels that are not supposed to be enabled according to the
+ regulatory rules.
+
+ This reverts commit 8eca1fb692cc9557f386eddce75c300a3855d11a.
