On my machine with single irq AHCI just the PCI id is printed as

I found a related discussion from beginning of this year:
http://www.gossamer-threads.com/lists/linux/kernel/2117335
Seems like commit commit 4f37b504768c952b64bc9469a2d579c7597590f2
^^^^^^ one is enough :-)
And scripts/checkpatch.pl now rnofrces certain format for the commit citing.
tried to fix displaying a proper interrupt description for one
scenario but broke it for another one.
The mentioned discussion ended in the current situation being
considered as broken but w/o a patch to fix it.
The following patch is based on a proposal in this mail thread.
Now the interrupt is properly described as:
PCI-MSI 512000-edge ahci[0000:00:1f.2]
By combining both values also the scenario that commit
4f37b504768c952b64bc9469a2d579c7597590f2 refers to should
still be fine. There it should look like this now:
ahci[20100000.ide]
s/ide/sata/?
Using managed memory allocation ensures that the irq description
lives at least as long as the interrupt.
