From 3b580144725ba6adc034713fe243e69c0f63dd05 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 25 Oct 2014 17:19:28 +0200 Subject: [PATCH] ath9k: fix processing RXORN interrupts The "goto chip_reset" is a bit misleading, because it does not actually issue a chip reset. Instead it is bypassing processing of other interrupts and assumes that the tasklet will issue a chip reset. In the case of RXORN this does not happen, so bypassing processing of other interrupts will simply allow them to fire again. Even if RXORN was triggering a reset, it is not critical enough to need the bypass here. Signed-off-by: Felix Fietkau Signed-off-by: John W.
