I can understand this from both sides ... I have contributed some some
stuff, or at least said I had it, and it never got put in the tree.
(It was low priority stuff.)  Also, being a port master, I have
received kernel patches that still do not show up in the -current
stuff for the pc532.  Part of the problem is time to verify that
things work correctly.  I just got bit by not verifying a patch sent
to me.  (Not a major problem, but it still was a bug that made me
think my hardware failed.)

So, please keep sending stuff to "us".  It may take a while for it to
appear due to several reasons, but (at least for me) I do like getting
stuff and it does help.  I do try to say "thanks, and it may not show
up for a while".

Keep up the good work all around.
