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!
