Merge tag 'gpio-fixes-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO fixes from Linus Walleij:
"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."
