Subject: [PATCH 4.4 117/118] genirq/msi: Fix broken debug output
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Gleixner <tglx@...utronix.de>
commit 4364e1a29be16b2783c0bcbc263f61236af64281 upstream.
virq is not required to be the same for all msi descs. Use the base irq number
from the desc in the debug printk.
