Indeed. Looking at the driver, all of the spin_lock_irq() usage in the
irqchip callbacks is broken.

So this needs two changes:

   1) Convert to raw spin lock, as this won't work on RT otherwise

   2) s/lock_irq/lock/ for all irqchip callbacks.

Are you sure about the calls in gpio_siox_get_data()? This is only
called by siox_poll() which doesn't disable irqs.

I explicitely said: "for all irqchip callbacks".

gpio_siox_get_data() is not a irq chip callback, right? So obviously it
has to stay there.

Thanks,
