Subject: net/ariadne: delete unneeded call to netdev_priv
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=688c3b003382c16be811072b4c6e88408672861c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net/ariadne: delete unneeded call to netdev_priv

Netdev_priv is an accessor function, and has no purpose if its result is
not used.

A simplified version of the semantic match that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@ local idexpression x; @@
-x = netdev_priv(...);
... when != x
// </smpl>
