Thank you for taking care of this!  Much appreciated!

Oh this somewhat awkward indentation we have with this ternary now,
and so I wonder if either:

	mask = (dev_to_node(dev) == NUMA_NO_NODE) ?
		cpu_online_mask : cpumask_of_node(dev_to_node(dev));

Or, perhaps (yes, a few more lines):

	if (dev_to_node(dev) == NUMA_NO_NODE)
		mask = cpu_online_mask;
	else
		mask = cpumask_of_node(node);

Would be easier on the eyes, so to speak.  What do you think (not a problem
if you don't want to change anything, thoguh)?

Thank you!
