From 74f82af1eda39c26c17f8030e4f60c00929ec9df Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 8 Dec 2008 21:31:32 -0700 Subject: ACPI: PCI: expand acpi_pci_allocate_irq() and acpi_pci_free_irq() inline acpi_pci_allocate_irq() and acpi_pci_free_irq() are trivial and only used once, so just open-code them.
