Subject: 3.19: device name associates with IRQ's for ahci controllers operating with a single IRQ changed from "ahci?" to "<BDF>"

Hi.

In 3.19 the device name associates with IRQ's for ahci controllers operating
with a single IRQ changed from "ahci?" to "<BDF>", was this intentional ?

It's probably commit 18dcf433f3ded61eb140a55e7048ec2fef79e723 (or another one
in that series).
