   4 Subject: [PATCH 2/2] mmc: sdhci-esdhc-imx: Fixup runtime PM conditions during
   5  ->probe()
   6
   7 By configure runtime PM prior we enable the use of it, we close the gap
   8 for strange and unhandled conditions. Moreover it makes us rely on the
   9 driver core, after finalized ->probe(), to request an inactive device
  10 to become runtime PM idle/suspended, which earlier potentially could
  11 happen already at pm_runtime_set_autosuspend_delay().
