Hello,

It may... but I've only got a fairly limited hardware testing setup, and 
this driver is used across a pretty broad set of hardware configured in 
various ways. So, I'm trying to limit the scope of things I might break. 
Initially I thought it was added to avoid a QEMU issue, but now I don't 
think that is the case.

So, if 0 can't be an interrupt why not update phy_interrupt_is_valid() 
to check for it? That would fix the problem too...
