[GIT PULL] libvdimm + dax fixes for v5.14-rc6

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-fixes-5.14-rc6

...to receive a couple fixes for long standing bugs, a warning fixup,
and some miscellaneous dax cleanups.

The bugs were recently found due to new platforms looking to use the
ACPI NFIT "virtual" device definition, and new error injection
capabilities to trigger error responses to label area requests. Ira's
cleanups have been long pending, I neglected to send them earlier, and
see no harm in including them now. This has all appeared in -next with
no reported issues.
