## Overview

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

rtc: amlogic-a4: fix double free caused by devm

The clock obtained via devm_clk_get_enabled() is automatically managed
by devres and will be disabled and freed on driver detach. Manually
calling clk_disable_unprepare() in error path and remove function
causes double free.

Remove the redundant clk_disable_unprepare() calls from the probe
error path and aml_rtc_remove(), allowing the devm framework to
automatically manage the clock lifecycle.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
