The sas address comparation of domain device and expander phy is open
coded. Now we can replace it with sas_phy_match_dev_addr().

It would be nice if the series was arranged such that 
sas_phy_match_dev_addr() is available when you introduce 
sas_phy_match_dev_addr()

Thanks,

I assume you mean sas_phy_match_dev_addr() should available before 
introducing sas_find_attached_phy().

Yes, I can make that change.

Thanks,
Jason
