Description

In the Linux kernel, the following vulnerability has been resolved:

gpio: arizona: Fix runtime PM leak in arizona_gpio_direction_out()

Switching a persistent GPIO line from input to output acquires a runtime PM reference on the parent device, but if the subsequent regmap_update_bits() fails the reference is never dropped and no later direction_in() can balance it since the direction was never changed. Drop the reference on the update failure path.
