Merge tag 'libnvdimm-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updayes from Vishal Verma:
 "You'd normally receive this pull request from Dan Williams, but he's
  busy watching a newborn (Congrats Dan!), so I'm watching libnvdimm
  this cycle.

  This adds a new feature in libnvdimm - 'Runtime Firmware Activation',
  and a few small cleanups and fixes in libnvdimm and DAX. I'd
  originally intended to make separate topic-based pull requests - one
  for libnvdimm, and one for DAX, but some of the DAX material fell out
  since it wasn't quite ready.

  Summary:

   - add 'Runtime Firmware Activation' support for NVDIMMs that
     advertise the relevant capability

   - misc libnvdimm and DAX cleanups"
