Subject: [TCP] MD5: Remove some more unnecessary casting.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b0a713e9e6091b30d0e615d2be88017a57f37c76;p=deliverable%2Flinux.git

[TCP] MD5: Remove some more unnecessary casting.

while reviewing the tcp_md5-related code further i came across with
another two of these casts which you probably have missed. I don't
actually think that they impose a problem by now, but as you said we
should remove them.
