Subject: ath9k: ignore led_pin if ath9k GPIO controller is used with DT
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b06559e5b76adfbafb16965098994cd30e8ded9c;p=openwrt%2Fstaging%2Flinusw.git

ath9k: ignore led_pin if ath9k GPIO controller is used with DT

Don't setup the default led pin if the ath9k GPIO controller is used
via device tree to prevent collision. In case any of the pins exposed
by the ath9k is used, the phyNtpt trigger needs to be set in userspace.
