ACPI_BUS_SCAN(9) Device drivers infrastructure ACPI_BUS_SCAN(9)NAMEacpi_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.
