From 44f8e1a20cf3afe10a3744bd9317808a39a242bb Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 2 Jul 2005 10:35:33 -0700 Subject: [PATCH] If ACPI doesn't find an irq listed, don't accept 0 as a valid PCI irq. That zero just means that nothing else found any irq information either. --- drivers/acpi/pci_irq.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/acpi/pci_irq.c b/drivers/acpi/pci_irq.c index 8dbf802ee7..d1f42b9728 100644 --- a/drivers/acpi/pci_irq.c +++ b/drivers/acpi/pci_irq.c @@ -433,7 +433,7 @@ acpi_pci_irq_enable ( printk(KERN_WARNING PREFIX "PCI Interrupt %s[%c]: no GSI", pci_name(dev), ('A' + pin)); /* Interrupt Line values above 0xF are forbidden */ - if (dev->irq >= 0 && (dev->irq <= 0xF)) { + if (dev->irq > 0 && (dev->irq <= 0xF)) { printk(" - using IRQ %d\n", dev->irq); acpi_register_gsi(dev->irq, ACPI_LEVEL_SENSITIVE, ACPI_ACTIVE_LOW); return_VALUE(0); -- 2.39.5
