Subject: [PATCH] media: gspca: remove redundant assignment to variable ret

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

The variable ret is being initialized with a value that
is never read and is being re-assigned a little later on. The
assignment is redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
