In variadic functions we still do the cast. In POSIX, it's not necessary, since NULL is required to be of type 'void *', and 'void *' is guaranteed to have the same alignment and representation as 'char *'. However, since ISO C still doesn't mandate that, and moreover they're doing dubious stuff by adding nullptr, let's be on the cautious side. Also, C++ requires that NULL is _not_ 'void *', but either plain 0 or some magic stuff. Signed-off-by: Alejandro Colomar <alx@kernel.org>
