+Subject: [PATCH 2/2] mmc: sdhci-esdhc-imx: Fixup runtime PM conditions during
+ ->probe()
+
+By configure runtime PM prior we enable the use of it, we close the gap
+for strange and unhandled conditions. Moreover it makes us rely on the
+driver core, after finalized ->probe(), to request an inactive device
+to become runtime PM idle/suspended, which earlier potentially could
+happen already at pm_runtime_set_autosuspend_delay().
