Subject: Fix a potential NULL pointer dereference in uli526x_interrupt() in drivers/net/tulip/uli526x.c
From: Micah Gruber <micah.gruber@xxxxxxxxx>
This patch fixes an apparent potential null dereference bug where we
dereference dev before a null check. This patch simply remvoes the
can't-happen test for a null pointer.
