The standby GPIO controller can be used as a interrupt controller.
Select GPIOLIB_IRQCHIP when compiling this driver. Otherwise we get
a compilation error:

Quan's patch exporting the symbols has been merged by tglx
so dropping this.

Thanks for the info.
Actually this is v1 [1] of the patch, which just addresses the
GPIOLIB_IRQCHIP problem?
With Quan's patch this should still be present.

Ah sorry I screwed up here and confused the patches.
Patch applied.

Hi Matthias,
I have acked your v1 as it helps fixing compile error if
CONFIG_GPIOLIB_IRQCHIP missing.
I also agreed with Linus on your v2.
Hence, I only acked the v2 patch if my patch
(https://lkml.org/lkml/2016/3/3/497) missed the merge windows as this
drivers can actually work as a module.

Thanks for the info.
Just as a heads up, this patch fix two problems. Apart from the missing
exports for the irqchip functions, it selects GPIOLIB_IRQCHIP as
otherwise the config may be broken.
Actually v1 of this patch just fixes this:

Quan has sent a patch exporting the offending functions, but no reply from
the irqchip maintainers yet.
If they don't react we'll have to merge this and handle the module loading
later.
