From 55bfe3c0c561783655a8ff2f6f3f19ac1362b132 Mon Sep 17 00:00:00 2001 From: Taku Izumi Date: Tue, 18 Sep 2012 15:22:35 +0900 Subject: PCI/ACPI: Pass acpi_pci_root to acpi_pci_drivers' add/remove interface This patch changes .add/.remove interfaces of acpi_pci_driver. In the current implementation acpi_handle is passed as a parameter of .add/.remove interface. However, the acpi_pci_root structure contains more useful information than just the acpi_handle. This enables us to avoid some useless lookups in each acpi_pci_driver. Note: This changes interfaces used by acpi_pci_register_driver(), an exported symbol. This patch updates all the in-kernel users, but any out-of-kernel acpi_pci_register_driver() users will need updates.
