Subject: Re: [RFC Patch v1 2/6] ACPI: rename acpi_evaluate_hotplug_ost to acpi_evaluate_ost for reuse

Hi Rafael,
	We have following code to deal with existing users.
+#ifdef ACPI_HOTPLUG_OST
+#define	acpi_evaluate_hotplug_ost	acpi_evaluate_ost
+#else
+static inline acpi_status
 acpi_evaluate_hotplug_ost(acpi_handle handle, u32 source_event,
-			u32 status_code, struct acpi_buffer *status_buf);
+			u32 status_code, struct acpi_buffer *status_buf)
+{ return AE_OK; }
+#endif

Thanks!
