Bug#445540: mdadm: checkarray typo exit0

[Helmut Grohne]

Package: mdadm
Version: 2.6.3+200709292116+4450e59-3
Severity: minor

Great work, especially /usr/share/doc/mdadm!

checkarray line 82 says:
    *) echo "$PROGNAME: E: invalid option: $opt" >&2; usage >&2; exit0;;

but there is no command exit0, so I suggest to replace it with:
    *) echo "$PROGNAME: E: invalid option: $opt" >&2; usage >&2; exit 0;;
