From fe7ef5e9ba0c60bab01390493a4c6790f7b093af Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 4 Dec 2012 15:07:34 +0100 Subject: regulatory: remove handling of channel bandwidth The channel bandwidth handling isn't really quite right, it assumes that a 40 MHz channel is really two 20 MHz channels, which isn't strictly true. This is the way the regulatory database handling is defined right now though so remove the logic to handle other channel widths.
