Subject: CVE-2023-52688: wifi: ath12k: fix the error handler of rfkill config

Description
===========

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

wifi: ath12k: fix the error handler of rfkill config

When the core rfkill config throws error, it should free the
allocated resources. Currently it is not freeing the core pdev
create resources. Avoid this issue by calling the core pdev
destroy in the error handler of core rfkill config.

Found this issue in the code review and it is compile tested only.

The Linux kernel CVE team has assigned CVE-2023-52688 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
