2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit f65515275ea3e45fdcd0fb78455f542d6fdca086 upstream.

In http://bugzilla.novell.com/show_bug.cgi?id=597299, the vt6655 driver
generates a kernel BUG on a NULL pointer dereference at NULL. This problem
has been traced to a failure in the wpa_set_wpadev() routine. As the vt6656
driver does not call this routine, the vt6655 code is similarly set to skip
the call.
