[patch 14/20] drivers/mmc/host/sdhci-s3c.c: use the correct mutex and card detect function

[akpm@linux-foundation.org]

From: Kyungmin Park <kyungmin.park@samsung.com>

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.
