Ah, you're right, and this was my bad. Looks like this change was
introduced in 3.2 and broke this and one more driver (ezx-pcap):

ARM: pxa: rename gpio_to_irq and irq_to_gpio

Avoid to define gpio_to_irq() and irq_to_gpio() for potential name
confliction since multiple architecture will be built together.

Haojian, I think it was probably premature to do the multiplatform
change like that, since it means that a PXA-only kernel has no mapping
from irq_to_gpio to pxa_irq_to_gpio. Can you please address this as a
fix for 3.4?
