Subject: [PATCH] spi: sh-msiof: remove redundant pointer dev

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

The pointer dev is assigned but never read, hence it is redundant
and can be removed. Cleans up clang warning:

drivers/spi/spi-sh-msiof.c:1198:2: warning: Value stored to 'dev'
is never read
