Gah... Your correct.
I think ni_gpct_device_destroy() should be changed to:
void ni_gpct_device_destroy(struct ni_gpct_device *counter_dev)
{
- if (!counter_dev->counters)
+ if (!counter_dev)
return;
kfree(counter_dev->counters);
kfree(counter_dev);
}
Then the NULL checks can be removed from the drivers.

I'm not sure either. But having is after the spin_lock_irqsave() didn't
make any sense.
ni_mio_common.c: ni_E_interrupt() has similar smp_mb() with a
comment so I made it the same here.
If you don't think they are necessary I don't have any issues with
removing them.
