[PATCH 1/2] drivers/net/r6040.c: adjust error handling

[Julia Lawall]

From: Julia Lawall <julia@xxxxxxx>

The just preceding error case does a lot of error handling, so it seems
like this one should as well.

The semantic match that found the problem is:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression E,E1,E2;
@@

E = alloc_etherdev(...)
... when != E = E1
if (...) { ... free_netdev(E); ... return ...; }
... when != E = E2
(
  if (...)
   {
   ... when != free_netdev(E);
   return dev; }
|
* if (...)
   {
   ... when != free_netdev(E);
   return ...; }
|
register_netdev(E)
)

// </smpl>
