From 409ef0bacacf72c51cc876349ae3fdf7cf726d47 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 10 Jul 2018 16:40:34 +0100 Subject: [PATCH] thermal_hwmon: Sanitize attribute name passed to hwmon 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.
