The __gpio_to_irq() function returns -ENXIO if the referenced gpio_chip structure does not define a to_irq() member. This is true of the asic3 gpio_chip structure, and thus calls to gpio_to_irq() now fail (for example from the gpio-vbus module). This patch defines the to_irq() member in the asic3 gpio_chip structure.
