From 7c350a2a0fe52264d5aa55b9f7823c78dbb222d9 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Wed, 1 Aug 2018 14:48:59 +0200 Subject: [PATCH] ARM: Odroid XU3: Fix the dwmci_exynos *priv data assignment for DM_MMC (sdr_timing) By convention for DM_MMC the host->priv is used to store struct udevice *dev pointer. Unfortunately, the legacy Exynos DW MMC code uses this field to store pointer to dwmci_exynos_priv_data struct Hence, we do need to get data in other way - namely by using container_of when host pointer is present. In this way the sdr_timing data is properly accessed.
