Log:
  Add a hint that "device ctl" kind of depends on "device iscsi".
  
  It actually doesn't - "device ctl" automatically pulls in ICL, which
  would normally be a part of iscsi.ko.  However, doing it that way makes
  iscsi.ko unloadable, and building ctl.ko without iscsi.ko (using
  MODULES_OVERRIDE) results in ctl.ko that is unloadable, due to missing
  symbols that would be resolved to iscsi.ko.  And since the symbols
  are named "icl_whatever", it's not obvious that it's iscsi.ko that's
  required.
  
  If there is a better way - let me know.
