Subject: [PATCH 4/9] ehea: don't use flush_scheduled_work()

From: Tejun Heo <[email-masked]>
Date: Sun, 12 Dec 2010 16:53:00 +0100

Directly cancel port->reset_task from ehea_shutdown_single_port()
instead.  As this cancels the work for each port on driver detach,
flushing system_wq from ehea_remove() or ehea_module_exit() is no
longer necessary.
