Subject: [PATCH] mmc: dw_mmc-exynos: remove redundant initialization of variable 'found'

From: Colin Ian King <colin.king@...onical.com>

The variable 'found' is being initialized with a value that is never read
and it is being updated later with a new value.  The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
