[ Upstream commit 409ef0bacacf72c51cc876349ae3fdf7cf726d47 ]
My Chromebook Plus (kevin) is spitting the following at boot time:
(NULL device *): hwmon: 'sbs-9-000b' is not a valid name attribute, please fix
Clearly, __hwmon_device_register is unhappy about the property name. Some investigation reveals that thermal_add_hwmon_sysfs doesn't sanitize the name of the attribute.
In order to keep it quiet, let's replace '-' with '_' in hwmon->type This is consistent with what iio-hwmon does since b92fe9e3379c8.
