About dbus patch in 12.0 branch of meta-ivi

HI Tolkien
When I'm working to upgrade GDP to morty branch and meta-ivi 12.0 branch, I got the pulseaudio running problem because of below dbus patch in meta-ivi.

• https://github.com/GENIVI/meta-ivi/blob/12.0/meta-ivi/recipes-core-ivi/dbus/dbus/capi-dbus-send-with-reply-and-block-delete-reply-on-error.patch
  Why do you create the patch? I just look into the patch and it may be workaround patch.

I also create temporal patch to upgrade GDP in https://github.com/chbae/meta-genivi-dev/commit/06097735afae7aa4f381a9a798e6a754d2f2054a.
Please give me your opinion.

Thanks
