[PATCH] net: ipv6: Removed unnecessary parenthesis

[PATCH] net: ipv6: Removed unnecessary parenthesis

[Arushi Singhal]

Removed parentheses on the right hand side of assignment, as they are
not required. The following coccinelle script was used to fix this
issue:

@@
local idexpression id;
expression e;
@@

id =
-(
e
-)

You sent me two patches for this:

http://patchwork.ozlabs.org/patch/744661/
http://patchwork.ozlabs.org/patch/744702/

The follow up one does not indicate v2, so I'm confused. I'm not sure
this is a resend or just a new version.

Another question that is not clear from your description is if you had
a look at the entire tree to find more spots like this, or you just
found this one and update it.

Ideally, it would be better to fix everything in one go, so we don't
have to deal with oneliner patches that just fix one single spot.

Thanks!
