Subject: [PATCH v2 0/4] blk-integrity: drop integrity_kobj from gendisk

The embedded member integrity_kobj member of struct gendisk violates
the assumption of the driver core that only one struct kobject should be
embedded into another object and then manages its lifetime.

As the integrity_kobj is only used to hold a few sysfs attributes it can
be replaced by direct device_attributes and removed.

Signed-off-by: Thomas Weißschuh <linux@...ssschuh.net>

Changes in v2:
- Get rid of integrity_kobj completely
- Migrate to sysfs_emit helper
- Link to v1: https://lore.kernel.org/r/20230309-kobj_release-gendisk_integrity-v1-1-a240f54eac60@weissschuh.net

      blk-integrity: use sysfs_emit
      blk-integrity: convert to struct device_attribute
      blk-integrity: register sysfs attributes on struct device
      blk-integrity: drop integrity_kobj from gendisk
