Subject: veth: Remove useless veth field
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bb7bba3d56963be59bc6764c8021290ed55205ad;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

veth: Remove useless veth field

The veth private structure contains a netdev pointer refering to its peer.
This field is never used and it is pointless because if we can access,
the veth_priv, that means we already have the netdev which is stored
in veth_priv->dev.
