platform_get_irq_byname() supported on ACPI?

[Timur Tabi <timur@codeaurora.org>]

Is there support for the platform_get_irq_byname() function on ACPI systems?

I'm working on adding ACPI support for a driver that currently only 
supports device tree.  This driver has code like this:

	ret = platform_get_irq_byname(pdev, "core0_irq");

This function works fine on device tree, but it fails on our ACPI system 
because our ACPI nodes don't appear to have any way to attach a name to 
an IRQ resource:

Method (_CRS, 0x0, Serialized) {
	Name (RBUF, ResourceTemplate() {
		[snip]
		Interrupt (ResourceConsumer, Level, ActiveHigh,
			Exclusive, , , )
			{0x120, 0x121, 0x122, 0x123}
	})
	Return (RBUF)
}

I would hate to have to do something like this:

ret = platform_get_irq_byname(pdev, "core0_irq");
if (ret)
	/* ACPI doesn't support named resources */
	ret = platform_get_irq(pdev, 0);
