Subject: net: tulip: delete useless tests on netdev_priv
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2d4dda781fc1e9c929a1f699119b91eddbcf475c;p=linux-beck.git

net: tulip: delete useless tests on netdev_priv

Netdev_priv performs an addition, not a pointer dereference, so it seems
quite unlikely that its result would ever be NULL.

A semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
statement S;
@@

- if (!netdev_priv(...)) S
// </smpl>
