Message-Id: <1403784834-23301-4-git-send-email-jeffrey.t.kirsher@intel.com> Date: Thu, 26 Jun 2014 05:13:42 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Mitch Williams <mitch.a.williams@...el.com>, netdev@...r.kernel.org, gospo@...hat.com, sassmann@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 03/14] i40evf: don't stop watchdog if it hasn't started From: Mitch Williams <mitch.a.williams@...el.com> If the VF driver fails to complete early init, then rmmod can cause a softlock when the driver tries to stop a watchdog timer that never even got initialized. Add a check to see if the timer is actually initialized before stopping it.
