This series up to this patch produces a build error that
would break git bisect:

drivers/gpio/gpio-omap.c: In function ‘omap_gpio_unmask_irq’:
drivers/gpio/gpio-omap.c:866:37: error: ‘gpio’ undeclared (first use in this function)
  unsigned int irq_mask = GPIO_BIT(bank, gpio);

Applying the following patch makes things build again.

Tony
