[PATCH 07/19] swim3: use bdev_check_media_changed

From: Christoph Hellwig
Date: Wed Sep 02 2020 - 10:30:10 EST


Switch to use bdev_check_media_changed instead of check_disk_change and
call floppy_revalidate manually. Given that floppy_revalidate only
deals with media change events, the extra call into ->revalidate_disk
from bdev_disk_changed is not required either, so stop wiring up the
method.
