Previously a new line is implicitly added in the no GSI case:
[ 7.185182] pci 0001:00:12.0: can't derive routing for PCI INT A
[ 7.191352] pci 0001:00:12.0: PCI INT A: no GSI
[ 7.195956] - using ISA IRQ 10
The code thus prints a blank line where no legacy IRQ is available:
[ 1.650124] pci 0000:00:14.0: can't derive routing for PCI INT A
[ 1.650126] pci 0000:00:14.0: PCI INT A: no GSI
[ 1.650126]
[ 1.650180] pci 0000:00:14.0: can't derive routing for PCI INT A
Fix this by making the newline explicit and removing the superfluous
one.

I think this is a better fix:

We're still seeing this in 3.7-rc3. Any preference to the approach here?
Thanks,
