Merge tag 'libnvdimm-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Ira Weiny:

 - One small cleanup to use sizeof(*pointer)

 - Add MODULE_DESCRIPTIONS() to eliminate make W=1 warnings

* tag 'libnvdimm-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
  testing: nvdimm: Add MODULE_DESCRIPTION() macros
  testing: nvdimm: iomap: add MODULE_DESCRIPTION()
  dax: add missing MODULE_DESCRIPTION() macros
  nvdimm: add missing MODULE_DESCRIPTION() macros
  ACPI: NFIT: add missing MODULE_DESCRIPTION() macro
  nvdimm/btt: use sizeof(*pointer) instead of sizeof(type)
