Subject: [PATCH] ath9k: fix double calls to ath_radio_enable
Date: Tue, 06 Apr 2010 12:05:01 -0700 [thread overview]
Message-ID: <4BBB85DD.10409@openwrt.org> (raw)
With the enable_radio being uninitialized, ath_radio_enable() might be
called twice, which can leave some hardware in an undefined state.
