That's actually hard to prove in general, because pnv-pci.h includes
linux/pci.h, linux/pci_hotplug.h, linux/irq.h, misc/cxl-base.h and
asm/opal-api.h. At least four of which aren't included directly by
api.c.

But I'll take you word for it :)

cheers

Sorry for the lack of details...

api.c doesn't do anything related to pci hotplug, nor to OPAL. This
happens in pci.c.

It includes cxl.h which includes misc/cxl-base.h.

The only generic irq bits are irq_hw_number_t, provided by linux/types.h,
and irq_find_mapping(), provided by linux/irqdomain.h, which is included
by misc/cxl-base.h -> linux/interrupt.h -> asm/irq.h.

Cheers (and congrats :)

I did compile test it before giving my Reviewed-by.
