#     Merge tag 'libnvdimm-fixes-5.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
#     
#     Pull libnvdimm fixes from Dan Williams:
#      "I debated holding this back for the v5.2 merge window due to the size
#       of the "zero-key" changes, but affected users would benefit from
#       having the fixes sooner. It did not make sense to change the zero-key
#       semantic in isolation for the "secure-erase" command, but instead
#       include it for all security commands.
#     
#       The short background on the need for these changes is that some NVDIMM
#       platforms enable security with a default zero-key rather than let the
#       OS specify the initial key. This makes the security enabling that
#       landed in v5.0 unusable for some users.
#     
#       Summary:
#     
#        - Compatibility fix for nvdimm-security implementations with a
#          default zero-key.
#     
#        - Miscellaneous small fixes for out-of-bound accesses, cleanup after
#          initialization failures, and missing debug messages"
