Multiple drivers handling hotplug-capable ACPI device nodes install notify handlers covering the same types of events in a very similar way. Moreover, those handlers are installed in separate namespace walks, although that really should be done during namespace scans carried out by acpi_bus_scan(). This leads to substantial code duplication, unnecessary overhead and behavior that is hard to follow. For this reason, introduce common code in drivers/acpi/scan.c for handling hotplug-related notification and carrying out device insertion and eject operations in a generic fashion, such that it may be used by all of the relevant drivers in the future. To cover the existing differences between those drivers introduce struct acpi_hotplug_profile for representing collections of hotplug settings associated with different ACPI scan handlers that can be used by the drivers to make the common code reflect their current behavior.
