void acpi_bus_hot_remove_device

(

void *

context

)

acpi_bus_hot_remove_device: hot-remove a device and its children : struct acpi_eject_event pointer (freed in this func)

Hot-remove a device and its children. This function frees up the memory space passed by arg context, so that the caller may call this function asynchronously through acpi_os_hotplug_execute().

int acpi_bus_register_driver

(

struct acpi_driver *

driver

)

acpi_bus_register_driver - register a driver with the ACPI bus : driver being registered

Registers a driver with the ACPI bus. Searches the namespace for all devices that match the driver's criteria and binds. Returns zero for success or a negative error status for failure.

)

acpi_bus_unregister_driver - unregisters a driver with the APIC bus : driver to unregister

Unregisters a driver with the ACPI bus. Searches the namespace for all devices that match the driver's criteria and unbinds.
