The problem was caused by the sc16is75x overlays not preparing the interrupt pin correctly, and should be fixed by this Pull Request: https://github.com/raspberrypi/linux/pull/6111
In about 45 minutes time you should be able to run "sudo rpi-update pulls/6111" to install a new kernel with the updated overlays. Be careful to back-up any important data - this is a beta kernel.
