Subject: [PATCH] memstick: remove redundant pointer data

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

The pointer 'data' is assigned but never read; it is redundant and can
be removed.  Cleans up clang warning:

drivers/memstick/host/tifm_ms.c:266:2: warning: Value stored to 'data'
is never read
