From a3ce5cc1a60fd2e237599d4b9bc247422a7523c2 Mon Sep 17 00:00:00 2001 From: Seth Forshee Date: Sat, 16 Jun 2012 07:47:50 -0500 Subject: [PATCH] brcm80211: smac: remove unused code for 40MHz channels This code has been kept around in anticipation of adding support for 40MHz channels, but subsequent patches to better integrate with mac80211 regulatory support will render it completely broken. Therefore we should go ahead and remove it. Keep these changes separate from other cleanup patches in order to make it easier to resurrect 40MHz channel support at some point in the future.
