[PATCH 4.2 098/110] thermal: exynos: Fix register read in TMU

From: Greg Kroah-Hartman
Date: Fri Nov 06 2015 - 14:23:48 EST

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


From: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx>

commit b28fec1324bf8f5010d2c3c5d57db4115bda66d4 upstream.

The value of emul_con was getting overwritten if the selected soc is
SOC_ARCH_EXYNOS5260. And so as a result we were reading from the wrong
register in the case of SOC_ARCH_EXYNOS5260.
