[PATCH v2] hwmon: (core) Use device name as a fallback in devm_hwmon_device_register_with_info

[Heiner Kallweit <hkallweit1@xxxxxxxxx>]

A number of network PHY drivers use the following code:

name = devm_hwmon_sanitize_name(dev, dev_name(dev));
if (IS_ERR(name))
	return PTR_ERR(name);
devm_hwmon_device_register_with_info(dev, name, ..);

Make this a generic fallback option and use the device name if no name
is provided to devm_hwmon_device_register_with_info(). This would allow
to simplify the affected drivers.
