Subject: [PATCH] hwmon: (aquacomputer_d5next) Fix an error handling path in aqc_probe()
Date:   Sun, 22 May 2022 15:14:23 +0200
Message-Id: <be6b955d50de140fcc96bd116150b435021bf567.1653225250.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

If no memory can be allocated, some resources still need to be released as
already done in the other error handling paths.

Fixes: 752b927951ea ("hwmon: (aquacomputer_d5next) Add support for Aquacomputer Octo")
