Sure, the original patch is in this PR: OpenAMP/libmetal#279 ; this is not merged in the openamp libmetal yet. So obviously I can't provide the fix for that patch either :)

@CV-Bowen feel free to add my patch to the same PR, or squash the fix into your original patch. I am not sure what is the plan forward with that PR.
