Subject[PATCH] drivers/net/r6040.c: Eliminate double sizeof
From: Julia Lawall <julia@diku.dk>

Taking sizeof the result of sizeof is quite strange and does not seem to be
what is wanted here.

This was fixed using the following semantic patch.
(http://www.emn.fr/x-info/coccinelle/)

expression E;
@@

- sizeof (
sizeof (E)
- )
