From b06559e5b76adfbafb16965098994cd30e8ded9c Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Wed, 22 Mar 2017 08:04:16 +0100 Subject: [PATCH] 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.
