## Overview

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

staging: wfx: fix an error handling in wfx_init_common()

One error handler of wfx_init_common() return without calling
ieee80211_free_hw(hw), which may result in memory leak. And I add
one err label to unify the error handler, which is useful for the
subsequent changes.

## Affected

- `linux_kernel < 5.10.111`
- `linux_kernel >= 5.11, < 5.15.34`
- `linux_kernel >= 5.16, < 5.16.20`
- `linux_kernel >= 5.17, < 5.17.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.17.3`
