I really would like to see agnostic drivers (when they don't need of*.h/acpi.h to be included as "proxy" headers). With this, the change probably needs to be separated from this patch. If you address as suggested, Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> ... The rest I haven't checked, it might be possible to do something similar there as well.
