From 4c48381786159ba3f3d8a33d967aeb049341a220 Mon Sep 17 00:00:00 2001 From: Sujith Date: Tue, 18 Aug 2009 10:51:52 +0530 Subject: ath9k: Fix TX poll cancelling In ath9k_stop(), tx_complete_work was being cancelled twice. This patch fixes it. Also, locking sc->mutex should be done at the beginning. Signed-off-by: Sujith Signed-off-by: John W.
