# Linux kernel: GPIO arizona driver leaks a runtime PM reference on failure

In the Linux kernel's arizona GPIO driver, a failed register update when switching a line to output leaves a runtime power-management reference held and never released. The sources describe a resource leak, not code execution or data exposure.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
