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 <ulf.hansson@linaro.org> --- Changes in v3: Change to pm_runtime_put(). Update commit message/header accordingly. Changes in v2: Move pm_runtime_put_noidle() after mmc_add_host(). --- drivers/mmc/host/mmci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
