A patch is attached. It also makes the lexer able to reconize CRLF as a
newline, which someone else needed. I didn't add any error messages in
the case of multicharacter strings. Perhaps it's not really Coccinelle's
problem...

Subject: [PATCH] include/net/genetlink.h: Allow genlmsg_cancel to accept a NULL
argument
nlmsg_cancel can accept NULL as its second argument, so for similarity,
this patch extends genlmsg_cancel to be able to accept a NULL second
argument as well.
