gianfar: Do not call device_set_wakeup_enable() under a spinlock
The gianfar driver calls device_set_wakeup_enable() under a spinlock, which causes a problem to happen after the recent core power management changes, because this function can sleep now. Fix this by moving the device_set_wakeup_enable() call out of the spinlock-protected area. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
