Subject: hwmon: (coretemp) Properly label the sensors
X-Git-Tag: v2.6.35-rc5~6^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f4f09b4be35d38d6e2bf22c989443e65e70fc4c;p=platform%2Fkernel%2Flinux-exynos.git

hwmon: (coretemp) Properly label the sensors

Don't assume that CPU entry number and core ID always match. It
worked in the simple cases (single CPU, no HT) but fails on
multi-CPU systems.
