Subject: [210/262] hwmon: (coretemp) Fix for non-SMP builds

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

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

From: Jean Delvare <khali@...ux-fr.org>

commit 2aba6cac2a84f3b80e11a680c34d55e7739b474d upstream.

The definition of TO_ATTR_NO in the non-SMP case is wrong. As the SMP
definition resolves to the correct value, just use this for both
cases.

Without this fix the temperature attributes are named temp0_* instead
of temp2_*, so libsensors won't pick them. Broken since kernel 3.0.
