of_irq_get() may return  any negative error number as well as 0 on
failure,
while the driver only checks for -EPROBE_DEFER, blithely continuing with
the call to gpiochip_set_chained_irqchip() -- that function expects the
parent IRQ as *unsigned int*, so would probably do nothing  when a large
IRQ number resulting from a conversion of a negative error number is
passed
to it, however passing 0 would probably work but the driver won't receive
valid GPIO bank interrupts.

Check for 'ret <= 0' instead and return -ENXIO from the driver's probe
iff
of_irq_get() returned 0.

Fixes: f9367793293d ("pinctrl: sirf: add sirf atlas7 pinctrl and gpio
support")

Patch applied!

   Thanks! But to which branch? I'm not seeing it in linux-pinctrl.git...

devel.

    Still not seeing the patch, perhaps you forgot to push?

It seems the SiRF people are not using upstream (see other mails) so I do
not see we need to expediate it to fixes.

    Up to you.

Yours,
