+Subject: [PATCH] ath: use CTL region from cfg80211 if unset in EEPROM
+
+Many AP devices do not have the proper regulatory domain programmed in
+EEPROM. Instead they expect the software to set the appropriate region.
+For these devices, the country code defaults to US, and the driver uses
+the US CTL tables as well.
+On devices bought in Europe this can lead to tx power being set too high
+on the band edges, even if the cfg80211 regdomain is set correctly.
+Fix this issue by taking into account the DFS region, but only when the
+EEPROM regdomain is set to default.
