sungem: update gp->reset_task flushing
gp->reset_task_pending is always set right before reset_task is scheduled and as there is no synchronization between the setting and scheduling, busy looping on reset_task_pending before flushing reset_task doesn't really buy anything. Directly flush gp->reset_task on suspend and cancel on detach. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S. Miller" <davem@davemloft.net> Cc: netdev@vger.kernel.org
