The error code is returned to user space in quite many cases; e.g. the voice allocator is called from PCM hw_params, too, and that's most of user-space programs do actually check. It could be a surprise if it's changed without much reason, may trigger unexpected behavior changes. Of course, if the error code must be corrected, we can fix it. But I don't see it in this patch description. thanks, Takashi
