Subject: [ 19/75] hwmon: (fam15h_power) Fix pci_device_id array

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

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

From: Guenter Roeck <guenter.roeck@...csson.com>

commit c3e40a9972428d6e2d8e287ed0233a57a218c30f upstream.

pci_match_id() takes an *array* of IDs which must be properly zero-
terminated.
