[PATCH 03/33] thermal: exynos: remove needless threshold_temp abstraction

From: Bartlomiej Zolnierkiewicz
Date: Thu Sep 18 2014 - 11:28:34 EST


reg->threshold_temp is used only in exynos_tmu_initialize() and
is accessed only on Exynos4210 (other SoC types don't even have
threshold_temp entry assigned in their struct exynos_tmu_registers
instances) so the register abstraction is not needed and can be
removed.

There should be no functional changes caused by this patch.
