Subject: drivers/mmc/host/sdhci-s3c.c: use the correct mutex and card detect function
From: Kyungmin Park <kyungmin.park@xxxxxxxxxxx>
There's some merge problem between sdhic core and sdhci-s3c host. After
mutex is changed to spinlock. It needs to use use spin lock functions and
use the correct card detection function.
