Subject[PATCH] usb: gadget: udc: renesas_usb3: remove redundant assignment to ret
Date
From: Colin Ian King <colin.king@canonical.com>

Variable ret is being initialized with a value that is never read and
ret is being re-assigned immediately after the initialization in both
paths of an if statement. This is redundant and can be removed.

Addresses-Coverity: ("Unused value")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
