But isn't the real problem that in the device tree case,
irq_get_irq_data(ndev->irq) will work becaus parsing an interrupt
from the device tree populates it correctly in platform_get_irq()

So to me it seems like a weakness in the platform_get_irq()
helper altogether.

Does the following work? (I can send as a separate patch for
testing if you like).

Almost. If you replace :

+    if (r->flags & IORESOURCE_BITS)

with:

+    if (r && (r->flags & IORESOURCE_BITS))

Then you can push a patch with my:

Now if you can make it in -rc2 or -rc3, this revert should be forgotten. But if
you can't make it for 3.20, I'll push for the revert.

So I think it's up to you now, and let's see what Gregh says about it.

Cheers.
