## Name

acpi_bus_scan — Add ACPI device node objects in a given namespace scope.

## Synopsis

`int acpi_bus_scan (` | acpi_handle handle`)`;

## Arguments

`handle`

  Root of the namespace scope to scan.

## Description

Scan a given ACPI tree (probably recently hot-plugged) and create and add found devices.

If no devices were found, -ENODEV is returned, but it does not mean that there has been a real error. There just have been no suitable ACPI objects in the table trunk from which the kernel could create a device and add an appropriate driver.

Must be called under acpi_scan_lock.
