Subject: crypto: ccp - A value assigned to a variable is never used
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a52c7b16ddf31ad6f4ccbc10a50b7ae48b35fd13;p=linux.git

crypto: ccp - A value assigned to a variable is never used

Fix the following whitescan warning:

Assigning value "64" to "dst.address" here, but that stored value is
overwritten before it can be used.
