From 9b93d392fdbd336b0f1558592010c0169801afa5 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Wed, 23 Nov 2016 18:36:02 +0900 Subject: [PATCH] mmc: dw_mmc: exynos: fix to call suspend callback The dw_mmc-exynos should be RPM_ACTIVE on probe() to call suspend callback of runtime PM in pm_runtime_force_suspend() during first system suspend. Also call pm_runtime_get_noresume() on probe() because it doesn't call suspend/resume callback by runtime PM now.
