From 47d6fa8014314cf139d407840a85a1bd14588561 Mon Sep 17 00:00:00 2001 From: Andre Detsch Date: Mon, 26 Apr 2010 07:27:07 +0000 Subject: tg3: Fix INTx fallback when MSI fails commit dc8bf1b1a6edfc92465526de19772061302f0929 upstream. tg3: Fix INTx fallback when MSI fails MSI setup changes the value of irq_vec in struct tg3 *tp. This attribute must be taken into account and restored before we try to do a new request_irq for INTx fallback. In powerpc, the original code was leading to an EINVAL return within request_irq, because the driver was trying to use the disabled MSI virtual irq number instead of tp->pdev->irq.
