Below is a patch replacing acpi_evaluate_hotplug_ost() with acpi_evaluate_ost()
and dropping the ACPI_HOTPLUG_OST which I don't believe is necessary at all.

On top of the current linux-next and your series.

Thanks,
Rafael

Subject: ACPI: Drop acpi_evaluate_hotplug_ost() and ACPI_HOTPLUG_OST

Replace acpi_evaluate_hotplug_ost() with acpi_evaluate_ost()
everywhere and drop the ACPI_HOTPLUG_OST symbol so that hotplug
_OST is supported unconditionally.
