## Overview

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

serial: ma35d1: Fix clock reference leak in ma35d1serial_probe()

of_clk_get() returns a clock with a reference that has to be released
with clk_put(). ma35d1serial_probe() never does that, so the reference
is leaked on the probe error paths and also when the port is removed.

Release it on the error paths and in ma35d1serial_remove().

## Affected

- `Linux >= 930cbf92db0184e327293d5e7089be0b08d46371 < 547c742f3b4acd4634eec47e9bff8731b55059a0`

- `Linux >= 930cbf92db0184e327293d5e7089be0b08d46371 < 1b303d383089aae7f20ad19fee15690486b935cb`
- `Linux >= 930cbf92db0184e327293d5e7089be0b08d46371 < 98401cf912fe8a081ef8e500c421b6d957b55a99`
