[GIT PULL] NVDIMM for 6.1

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm 
tags/libnvdimm-for-6.1

...to receive some small cleanups and fixes in and around the nvdimm
subsystem. The most significant change is a regression fix for nvdimm
namespace (volume) creation when the namespace size is smaller than 2MB.

It has appeared in linux-next with no reported issues.
