[v2] hwmon: (aquacomputer_d5next) Add Aquacomputer Aquaero control

[PATCH v2 1/6] hwmon: (aquacomputer_d5next) Support one byte control values

Posted by Leonard Anderweit 2 years, 6 months ago

Add support for one byte control values. This extends aqc_set_ctrl_val() and
aqc_get_ctrl_val() with a type. Currently supported types are AQC_8 (one byte)
and AQC_BE16 (two bytes big endian). More types will be added in the future.

Applied. In the future, please make sure that the line length in the
description has no more than 75 columns.

Thanks,
