hwmon: (asus-ec-sensors) autoload module via DMI data
Browse files Browse the repository at this point in the history
Replace autoloading data based on the ACPI EC device with the DMI
records for motherboards models. The ACPI method created a bug that when
this driver returns error from the probe function because of the
unsupported motherboard model, the ACPI subsystem concludes
that the EC device does not work properly.

Fixes: 5cd2901 ("hwmon: (asus-ec-sensors) introduce ec_board_info struct for board data")
