Subject: thermal: exynos: Fix register read in TMU
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.
