# acpi\_scan\_drop\_device(9)

Drop an ACPI device object.

## NAME

acpi\_scan\_drop\_device - Drop an ACPI device object.

## SYNOPSIS

**void acpi\_scan\_drop\_device(acpi\_handle** *handle***, void \*** *context***);**

## ARGUMENTS

*handle*

Handle of an ACPI namespace node, not used.

*context*

Address of the ACPI device object to drop.

## DESCRIPTION

This is invoked by **acpi\_ns\_delete\_node** during the removal of the ACPI namespace node the device object pointed to by *context* is attached to.

The unregistration is carried out asynchronously to avoid running **acpi\_device\_del** under the ACPICA's namespace mutex and the list is used to ensure the correct ordering (the device objects must be unregistered in the same order in which the corresponding namespace nodes are deleted).
