Merge branch 'pci/yinghai-survey-resources+acpi-scan' into next
* pci/yinghai-survey-resources+acpi-scan: ACPI / scan: Treat power resources in a special way ACPI: Remove unused struct acpi_pci_root.id member ACPI: Drop ACPI device .bind() and .unbind() callbacks ACPI / PCI: Move the _PRT setup and cleanup code to pci-acpi.c ACPI / PCI: Rework the setup and cleanup of device wakeup ACPI: Add .setup() and .cleanup() callbacks to struct acpi_bus_type ACPI: Make acpi_bus_scan() and acpi_bus_add() take only one argument ACPI: Replace ACPI device add_type field with a match_driver flag ACPI: Drop the second argument of acpi_bus_scan() ACPI: Remove the arguments of acpi_bus_add() that are not used ACPI: Remove acpi_start_single_object() and acpi_bus_start() ACPI / PCI: Fold acpi_pci_root_start() into acpi_pci_root_add() ACPI: Change the ordering of acpi_bus_check_add() ACPI: Replace struct acpi_bus_ops with enum type ACPI: Reduce the usage of struct acpi_bus_ops ACPI: Make acpi_bus_add() and acpi_bus_start() visibly different ACPI: Change the ordering of PCI root bridge driver registrarion ACPI: Separate adding ACPI device objects from probing ACPI drivers
