Subject: [PATCH] ACPI: Rename acpi_scan_device_not_present() to be about
 enumeration

From: James Morse <james.morse@....com>

acpi_scan_device_not_present() is called when a device in the
hierarchy is not available for enumeration. Historically enumeration
was only based on whether the device was present.

To add support for only enumerating devices that are both present
and enabled, this helper should be renamed. It was only ever about
enumeration, rename it acpi_scan_device_not_enumerated().

No change in behaviour is intended.

This is another patch from James' aarch64 hotplug vcpu series.

I asked:

to which Jonathan Cameron replied:

So let's get this queued up.
