From 7da5d406792eedb5341a8c20296470b2e67743e7 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sun, 8 Oct 2006 07:41:19 -0600 Subject: [PATCH] [PATCH] i386/x86_64: FIX pci_enable_irq to set dev->irq to the irq number In commit ace80ab796ae30d2c9ee8a84ab6f608a61f8b87b I removed the weird logic that used the vector number as the irq number when MSI was defined. However pci_enable_irq was using a different test in the io_apic_assign_irqs path and I missed it :( This patch removes the wrong code so no one hits this problem. This code is only active when a specific set of boot command line parameters is specified which likely explains why no one has notices this earlier. Signed-off-by: Eric W.
