Subject: [ath9k-devel] [PATCH] ath9k: really disable DFS if
 CONFIG_ATH9K_DFS_CERTIFIED is not set

Currently ath9k allows hostapd to initialize radiation on DFS-channels
even when CONFIG_ATH9K_DFS_CERTIFIED is not set. This is due to the
advertised radar detection widths. This patch makes them depend on
CONFIG_ATH9K_DFS_CERTIFIED.
