## Overview

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

pinctrl: freescale: Fix a memory out of bounds when num_configs is 1

The config passed in by pad wakeup is 1, when num_configs is 1,
Configuration [1] should not be fetched, which will be detected
by KASAN as a memory out of bounds condition. Modify to get
configs[1] when num_configs is 2.

## Affected

- `Linux >= 3e84956605aca55a8c4280f0cf6230905c6f237d < 0d200240038bc40b1b073a3fd978764c829af77f`
