Subject: [PATCH v3 0/4] gpiolib: get rid of exessive ->of_gpio_ranges_fallback()

The ->of_gpio_ranges_fallback() repeats the idea that lies behind
->add_pin_ranges(), while the latter covers more cases that the former
hook. Drop the former one for good.

Changelog v3:
- moved check of the property presense to GPIO library
- split out the refcount fix in a separate patch
- added cover letter

Andy Shevchenko (4):
  gpiolib: Check "gpio-ranges" before calling ->add_pin_ranges()
  pinctrl: bcm2835: Remove of_node_put() in
    bcm2835_of_gpio_ranges_fallback()
  pinctrl: bcm2835: Switch to use ->add_pin_ranges()
  Revert "gpiolib: of: Introduce hook for missing gpio-ranges"
