gpio: siox: explicitly support only threaded irqs
The gpio-siox driver uses handle_nested_irq() to implement its
interrupt support. This is only capable of handling threaded irq
actions. For a hardirq action it triggers a NULL pointer oops.
(It calls action->thread_fn which is NULL then.)
Prevent registration of a hardirq action by setting
gpio_irq_chip::threaded to true.
