Thanks, applied... or almost. Let's fix it incrementally.
You have two smatch warnings: CHECK ../drivers/memory/samsung/exynos5422-dmc.c drivers/memory/samsung/exynos5422-dmc.c:272 exynos5_init_freq_table() warn: passing devm_ allocated variable to kfree. 'dmc->opp' CHECK ../drivers/memory/jedec_ddr_data.c drivers/memory/samsung/exynos5422-dmc.c:565 exynos5_dmc_get_volt_freq() warn: passing zero to 'PTR_ERR'
The second looks like false positive, but first seems to be real.
You have also sparse warning to fix: ../drivers/memory/samsung/exynos5422-dmc.c:736:1: warning: symbol 'exynos5_dmc_align_init_freq' was not declared. Should it be static?
Best regards, Krzysztof
