Subject: [PATCH] staging: unisys: visorhba: remove redundant initialization of variables scsicmd_id and rc

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

The variables scsicmd_id and rc is being initialized with a value
that is never read and are being updated later with a new value.
The initializations are redundant and can be removed.

Addresses-Coverity: ("Unused value")
