Subject: [PATCH] scsi: sym53c8xx_2: remove redundant assignment to retv

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

Variable retv is initialized to a value that is never read and it
is re-assigned later. The initialization is redundant and can be
removed.

Addresses-Coverity: ("Unused value")
