[PATCH v2 02/33] thermal: exynos: remove needless tmu_status abstraction

From: Bartlomiej Zolnierkiewicz
Date: Thu Nov 13 2014 - 10:02:25 EST


reg->tmu_status is used only in exynos_tmu_initialize() and it
is accessed only if TMU_SUPPORT_READY_STATUS flag is set. This
flag is not set for Exynos5440 and TMU_STATUS register offset
is identical for all other SoC types so the abstraction is not
needed and can be removed.

There should be no functional changes caused by this patch.
