Previously the pm_runtime_put() caused the device to be runtime PM suspended, but then immediately being resumed when we add the host.
Prevent this unnecessary runtime PM suspend/resume cycle during ->probe() by moving the call to pm_runtime_put() after mmc_add_host(). Signed-off-by: Ulf Hansson <[email protected]> --- Changes in v3: Change to pm_runtime_put(). Update commit message/header accordingly.
