My concerns are: - not so standard format of representation (why not to use string_escape_mem() helper?) or is it? - no compatibility with generic 4cc (I would rather have an additional specifier here for v4l2 cases. OTOH generic %p4cc to me sounds like an equivalent to %4pEh (but we have similar cases with MAC where %6ph is the same as %pM). But I'm not insisting on them, consider it like just my 2 cents to the discussion. -- With Best Regards, Andy Shevchenko
