Wireshark-dev: Re: [Wireshark-dev] [Wireshark-commits] rev 53895: /trunk/ /trunk/asn1/disp/: pa

Should all of these null checks be handled in one place (like
call_dissector_through_handle or something)?

Are there specific dissectors where it's valid for data to be NULL?
Even if there are, is it simply less work at this point to pass them a
pointer to an empty struct or some such thing?
