[GIT PULL] libnvdimm + device-dax for v5.12-rc1

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.12

...to receive some miscellaneous cleanups and a fix for v5.12. This
mainly continues the kernel wide effort to remove a return code from
the remove() callback in the driver model. The fix addresses a return
code polarity typo in the new sysfs attribute to manually specify a
device-dax instance mapping range. This has all appeared in -next with
no reported issues.
