Subject: [ 029/108] hwmon: (ad7314) Add name sysfs attribute

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

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

From: Guenter Roeck <linux@...ck-us.net>

commit 3ceefe4319636d89d4bdf40dca9471970f942e4f upstream.

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