Subject: [PATCH v2 3/6] hwmon: (aquacomputer_d5next) Device dependent control report settings
Date:   Tue, 14 Feb 2023 23:02:18 +0100
Message-Id: <20230214220221.15003-4-leonard.anderweit@gmail.com>

Add device dependent control report id, secondary control report id, secondary
control report size and secondary control report for devices which need
different control report settings. All currently supported devices use the same
values.
