Actually, reverted, you didn't test this patch at all.

You didn't even look at the warnings emitted by the compiler
with your changes installed.

You're passing a network device pointer into the PCI device
disable routine, which takes a PCI device pointer.

I can't express to you how extremely irritating it is when
people submit patches like this.

The bug in question is 1,000 times less harmful than your fix.
