This patch looks useful, and I this does seem like a logical place to export this information. however, I'd think that an empty attribute instead of "No description" is sufficient to cover the case of _STR existing, but for some reason failing to evaluate. thanks, Len Brown, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
