 - Use configfs for config stuff.  This will require changes to the
   user space code.
 
-- Check the calls to tty_register_device.  In particular, check to see
-  if there should be some handling for IS_ERR(classp).
-
 - dgrp_send() and dgrp_receive() could use some refactoring
+
+- Don't automatically create CHAN_MAX (64) channel array entries for
+  every device as many devices are going to have much less than 64
+  channels.
+
+- The locking needs to be checked.  It seems haphazardly done in most
+  places.
