Subject: [PATCH 3.13 064/149] x86_pkg_temp_thermal: Do not expose as a hwmon device

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

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

From: Jean Delvare <jdelvare@...e.de>

commit 79786880a47a8c5b4c8146c03432b3387a07a169 upstream.

The temperature value reported by x86_pkg_temp_thermal is already
reported by the coretemp driver. So, do not expose this thermal zone
as a hwmon device, because it would be redundant.
