From 55821324dc6a10fab36871534a322bad159fad79 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 17 Dec 2010 00:57:01 +0100 Subject: [PATCH] ath9k_hw: remove baseband rfsilent support When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to turn off based on GPIO input, however that code was hardcoded to GPIO 0 instead of ah->rfkill_gpio. Since ath9k uses software rfkill anyway, this code is completely unnecessary and should be removed in case anything else ever uses GPIO 0. Signed-off-by: Felix Fietkau Signed-off-by: John W.
