ACPI: misc cleanups
This patch contains the following possible cleanups:
- make the following needlessly global code static:
- drivers/acpi/bay.c:dev_attr_eject
- drivers/acpi/bay.c:dev_attr_present
- drivers/acpi/dock.c:dev_attr_docked
- drivers/acpi/dock.c:dev_attr_flags
- drivers/acpi/dock.c:dev_attr_uid
- drivers/acpi/dock.c:dev_attr_undock
- drivers/acpi/pci_bind.c:acpi_pci_unbind()
- drivers/acpi/pci_link.c:acpi_link_lock
- drivers/acpi/sbs.c:acpi_sbs_callback()
- drivers/acpi/sbshc.c:acpi_smbus_transaction()
- drivers/acpi/sleep/main.c:acpi_sleep_prepare()
- #if 0 the following unused global functions:
- drivers/acpi/numa.c:acpi_unmap_pxm_to_node()
- remove the following unused EXPORT_SYMBOL's:
- acpi_register_gsi
- acpi_unregister_gsi
- acpi_strict
- acpi_bus_receive_event
- register_acpi_bus_type
- unregister_acpi_bus_type
- acpi_os_printf
- acpi_os_sleep
- acpi_os_stall
- acpi_os_read_pci_configuration
- acpi_os_create_semaphore
- acpi_os_delete_semaphore
- acpi_os_wait_semaphore
- acpi_os_signal_semaphore
- acpi_os_signal
- acpi_pci_irq_enable
- acpi_get_pxm
