From: Bartlomiej Zolnierkiewicz Date: Thu, 31 Jul 2014 17:11:01 +0000 (+0200) Subject: thermal: exynos: remove redundant pdata checks from exynos_tmu_initialize() X-Git-Tag: v4.9.8~5397^2~12 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=930aa102e2b0ba70ea420999362e2edc4fda15d3;p=platform%2Fkernel%2Flinux-rpi3.git thermal: exynos: remove redundant pdata checks from exynos_tmu_initialize() 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.
