ubiupdatevol: fix -t parameter
The execution of |./ubiupdatevol /dev/ubi0 -t will fail because 'argv[optind + 1]' is undefined and the later executed 'strcmp(args.img, "-")' will segfault. So I can hack around and supply a dummy image or fix it that way. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
