From ea110733874d5176cb56dcf612a629ffac09dbf0 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 13 Jun 2011 16:21:26 +0000 Subject: net: Remove casts of void * Unnecessary casts of void * clutter the code. These are the remainder casts after several specific patches to remove netdev_priv and dev_priv.
