From ebc43d093b38262f1fc51018a50892ce3a144852 Mon Sep 17 00:00:00 2001 From: James A Shackleford Date: Sat, 31 May 2014 20:09:05 -0400 Subject: [PATCH] staging: vt6655: fix sparse warning "cast removes address space of expression" Add missing __user macro to second parameter of ethtool_ioctl(). This removes the need for the offending (void *) cast of the user space pointer rq->ifr_data.
