I applied this patch yesterday, I see both changes here related to the
issue presented (confusing printing of len) so I'm fine with not
touching the other parts.

That said, there are a few other format strings in this driver that
would benefit from some love as well, several cases where we should use
%pK or %pad rather than using %llx and a cast to unsigned long long.
