From c35268f589d545fb4da5f4231fdc6c523a3724d3 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 26 Apr 2018 13:51:23 +0200 Subject: thermal: exynos: make ->tmu_initialize method void All implementations of ->tmu_initialize always return 0 so make the method void and convert all implementations accordingly. There should be no functional changes caused by this patch.
