From 3e30968e55e43ef08ee08c71258711a79c550f25 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Tue, 25 Sep 2007 20:56:36 +0200 Subject: [PATCH] [PATCH] rt2x00: make rt2x00lib_stop_link_tuner() reentrant with link_tuner work Calling cancel_delayed_work_sync() unconditionally won't hurt and it will avoid race conditions when another CPU is already executing link_tuner work.
