These are some GPIO regression fixes for v3.6: 

- Erroneous debug message from of_get_named_gpio_flags()
 - Make sure the MC9S08DZ60 GPIO driver depend on I2C being
   compiled in (not module) or allmodconfig breaks.
 - Check return value from irq_alloc_descs() in the Emma
   Mobile GPIO driver.
 - Assign the owner field for the rdc321x driver so the
   module won't be removed if it has active GPIOs.
