Subject: [PATCH] thermal/drivers/tsens: fix slope values for msm8939
Git-commit: 5aec3b035e0cbf3f042c2a03d654e5ad6748feb7
Patch-mainline: v6.3-rc1
References: git-fixes

According to the vendor kernels (msm-3.10, 3.14 and 3.18), msm8939
uses non-standard slope values for calibrating the sensors. Fill them
accordingly.
