From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>

3.5-stable review patch. If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <linux@xxxxxxxxxxxx>

commit 4e21f4eaa49f78d3e977e316514c941053871c76 upstream.

The 'name' sysfs attribute is mandatory for hwmon devices, but was missing
in this driver.
