The compiler is not happy when neither USB nor TFTP transport for DFU defined:

cmd/dfu.c: In function ‘do_dfu’:
cmd/dfu.c:31:8: warning: unused variable ‘devstring’ [-Wunused-variable]
  char *devstring = argv[3];
        ^~~~~~~~~
cmd/dfu.c:30:8: warning: unused variable ‘interface’ [-Wunused-variable]
    char *interface = argv[2];
          ^~~~~~~~~

Surround those variables by #ifdef expression.

More serious, that comes under same circumstances, is a compilation error due
to absence of macro parameter:

In file included from include/image.h:45,
                 from include/common.h:35,
                 from cmd/dfu.c:13:
include/command.h:207:24: error: expected expression before ‘,’ token
 # define _CMD_HELP(x) x,
                        ^
include/command.h:286:18: note: in expansion of macro ‘_CMD_HELP’
    _cmd, _usage, _CMD_HELP(_help) _CMD_COMPLETE(_comp) }
                  ^~~~~~~~~
include/command.h:290:3: note: in expansion of macro ‘U_BOOT_CMD_MKENT_COMPLETE’
   U_BOOT_CMD_MKENT_COMPLETE(_name, _maxargs, _rep, _cmd, \
   ^~~~~~~~~~~~~~~~~~~~~~~~~
include/command.h:332:2: note: in expansion of macro ‘U_BOOT_CMD_COMPLETE’
  U_BOOT_CMD_COMPLETE(_name, _maxargs, _rep, _cmd, _usage, _help, NULL)
  ^~~~~~~~~~~~~~~~~~~

 ^~~~~~~~~~
make[1]: *** [scripts/Makefile.build:279: cmd/dfu.o] Error 1
make: *** [Makefile:1518: cmd] Error 2

Put empty string unconditionally to have macro parameter present.

I can only recommend using patman, which shall link the dfu: in topic

Regarding the patch,

If the travis doesn't complain, feel free to apply it.

It's pity that different projects based on Kbuild infra are using
different type of accessing to maintainers data base.
I have used get_maintainer.pl.

get_maintainer.pl failed to report e-mail address since the
dfu command code entry is not in the data base file. I've just
sent a patch to fix it.
