Merge tag 'libnvdimm-fix-5.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm fix from Dan Williams:
 "A minor regression fix.

  The libnvdimm unit tests were expecting to mock calls to
  ioremap_nocache() which disappeared in v5.5-rc1. This fix has appeared
  in -next and collided with some cleanups that Christoph has planned
  for v5.6, but he will fix up his branch once this goes in.

  Summary:

   - Restore the operation of the libnvdimm unit tests after the removal
     of ioremap_nocache()"
