[PATCH] Fix printing when no interrupt is allocated

From: Daniel J Blueman
Date: Thu Oct 18 2012 - 20:34:05 EST


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.
