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.
