Subject: [PATCH] media: imx274: fix missing return assignment from call to imx274_mode_regs

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

The variable ret is being checked for failure however it is not being set
from the return status from the call to imx274_mode_regs. Currently ret is
alwayus zero and the check is redundant. Fix this by assigning it.

Detected by CoverityScan, CID#1460278 ("Logically dead code")
