[PATCH 2/2] mpd: Patch mpd to deal with format function being const in fmt-11.0.0 onwards

[Adolf Belka <adolf.belka@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 4630 bytes --]

- Commit has been made in mpd but no release has yet been made with the change. When the
   next version release of mpd occurs this patch can be removed.
- The patch changes all format calls to be const . Without this patch mpd will not build
   with fmt-11.0.0 or newer.
- Update of rootfile not required.
