Subject[09/15] gpio/pca953x: Fix warning of enabled interrupts in handler
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Jander <david@protonic.nl>

commit 6dd599f8af0166805951f4421a78ba716d78321a upstream.

When using nested threaded irqs, use handle_nested_irq(). This function
does not call the chip handler, so no handler is set.
