In [1] Geert just put the vendor directly into "family", while Imran uses "Snapdragon" (which I find reasonable in the Qualcomm case). But it seems like Geert would like a "vendor" as well, rather than a "family". And if "family" really is supposed to contain the "SoC family name" and we're trying to provide user space with some useful information (for some reason), should we just rely on the unlikeliness of two vendors using the same family name?
