[PATCH v4 05/13] gpio: adp5585: use devm_blocking_notifier_chain_register()
From: Eliav Farber <hidden>

Also in:
linux-acpi, linux-gpio, linux-iio, linux-pwm, lkml, platform-driver-x86
Subsystem:
adp5585 gpio expander, pwm and keypad controller driver, gpio subsystem, the rest · Maintainers:
Laurent Pinchart, Linus Walleij, Bartosz Golaszewski, Linus Torvalds
Replace the blocking_notifier_chain_register() + devm_add_action_or_reset() pattern with a single call to devm_blocking_notifier_chain_register(), removing the adp5585_gpio_unreg_notifier() callback.
