The hisi_gpio->line is unsigned int so the format specifier
should have been %u not %d.

Convert the driver to immutable irq-chip with a bit of
intuition.
The IRQ chip was unnamed which seems unwise, so we just
assign the name "HISI-GPIO".

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

This GPIO driver is for HiSilicon's ARM SoC.
HiSilicon's GPIO controller support double-edge interrupt and multi-core
concurrent access.
ACPI table example for this GPIO controller:
Device (GPO0)
{
Name (_HID, "HISI0184")
Device (PRTA)
{
Name (_ADR, Zero)
Name (_UID, Zero)
Name (_DSD, Package (0x01)
{
Package (0x02)
{
"ngpios",
0x20
}
})
}
}
