From 79d4db1214a0c7b1818aaf64d0606b17ff1acea7 Mon Sep 17 00:00:00 2001 From: Miaoqing Pan Date: Mon, 7 Mar 2016 10:38:17 +0800 Subject: [PATCH] ath9k: cleanup led_pin initial Make ath_init_leds() and ath_deinit_leds() pairs as the only API to set leds, also removed direction configuration from ath9k_start() and ath9k_stop(). So the initial is more clear now.
