Yeah, that was what I thought exactly when I saw it:
struct sock *sk = tun->sk; // initialize sk with tun->sk
return POLLERR; // if tun is NULL return error
It is _way_ to late to check once tun has already been used. The rest is just other problems that may exist already in the kernel.
PS. I am not the author of that article, despite having the same first name.
