## Overview

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

pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER

In create_pinctrl(), pinctrl_maps_mutex is acquired before calling
add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl()
calls pinctrl_free(). However, pinctrl_free() attempts to acquire
pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to
a potential deadlock.

This patch resolves the issue by releasing pinctrl_maps_mutex before
calling pinctrl_free(), preventing the deadlock.

This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

## Affected

- `linux_kernel >= 3.10, < 4.19.317`
- `linux_kernel >= 4.20, < 5.4.279`
- `linux_kernel >= 5.5, < 5.10.221`
- `linux_kernel >= 5.11, < 5.15.162`
- `linux_kernel >= 5.16, < 6.1.97`
- `linux_kernel >= 6.2, < 6.6.37`
- `linux_kernel >= 6.7, < 6.9.8`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.8`
