From bf4b1d070aeb3669d4b4e95c59c404d0e055c41c Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 15 Apr 2011 00:41:43 +0200 Subject: ath9k: fix the return value of ath_stoprecv commit 2232d31bf18ba02f5cd632bbfc3466aeca394c75 upstream. The patch 'ath9k_hw: fix stopping rx DMA during resets' added code to detect a condition where rx DMA was stopped, but the MAC failed to enter the idle state. This condition requires a hardware reset, however the return value of ath_stoprecv was 'true' in that case, which allowed it to skip the reset when issuing a fast channel change.
