This is not the first patch from issues reported by Zeal Robot
with an inappropriate subject. "drivers/hwmon:" doesn't say anything.
The subject should either be "<subsystem>: <driver>: <description>" or,
as commonly used in hwmon, "hwmon: (driver) <description". I fixed
the subject and applied the patch, but don't expect me to do this
again in the future.
