Markus Armbruster adds: The i82078 floppy device model used to call bdrv_media_changed() to implement its media change bit when backed by a host floppy. This went away in 21fcf36 "fdc: simplify media change handling". Probably broke host floppy media change. Host floppy pass-through was dropped in commit f709623. bdrv_media_changed() has never been used for anything else. Remove it.
