From a37a99102e4573145aa60a2f78a690cc8def027c Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 23 May 2013 12:20:55 +0200 Subject: ath9k_hw: fix host interface reset on AR934x If a local bus timeout has been detected, the host interface needs to be reset to clear the errors. AR934x uses a different synchronous interrupt bit to indicate this, so the check needs to be fixed. Signed-off-by: Felix Fietkau Signed-off-by: John W.
