Merge tag 'libnvdimm-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull nvdimm and DAX updates from Vishal Verma:
"This is mostly small cleanups and fixes, with the biggest change being
the change to the DAX fault handler allowing it to return
VM_FAULT_HWPOISON.
Summary:
- DAX fixes and cleanups including a use after free, extra
references, and device unregistration, and a redundant variable.
- Allow the DAX fault handler to return VM_FAULT_HWPOISON
- A few libnvdimm cleanups such as making some functions and
variables static where sufficient.
- Add a few missing prototypes for wrapped functions in
tools/testing/nvdimm"
