Subject: [PATCH v3 3/8] thermal: exynos: remove redundant pdata checks from exynos_tmu_initialize()
Date: Thu, 31 Jul 2014 19:11:01 +0200	[thread overview]
Message-ID: <1406826667-2289-4-git-send-email-b.zolnierkie@samsung.com> (raw)
In-Reply-To: <1406826667-2289-1-git-send-email-b.zolnierkie@samsung.com>

Remove runtime checks for pdata sanity from exynos_tmu_initialize().

The current values hardcoded in pdata will never trigger the checks
and checking itself is not proper.  The checks in question are done
at runtime in a production code for data that is hardcoded inside
driver during development time and later it doesn't change.  Such
data should be verified during development and review time (i.e. by
a script parsing relevant data from exynos_tmu_data.c, one can also
argue that verification to be done is so simple that the review by
a maintainer should be enough).

There should be no functional changes caused by this patch.
