Seems like the right solution if we should have run-time loaded
IRQchips.
Acked-by: Linus Walleij <[email protected]>
This causes a build error in -next so if it's not solved before the merge window
we may have to mark the xgene standby driver as bool to overcome the problem.
Yours,
Linus Walleij

genirq: Export IRQ functions for module use
Export irq_chip_*_parent(), irq_domain_create_hierarchy(),
irq_domain_set_hwirq_and_chip(), irq_domain_reset_irq_data(),
irq_domain_alloc/free_irqs_parent()
So gpio drivers can be built as modules. First user: gpio-xgene-sb
