[PATCH v2 0/4] ACPI: NFIT: core: Fix multiple issues related to concurrency and cleanup

[Rafael J. Wysocki]

Hi All,

This series is a replacement for

https://lore.kernel.org/linux-acpi/6000262.DvuYhMxLoT@rafael.j.wysocki/

and it addresses some additional issues discovered during the review
of the patch above.  Some of it is based on the sashiko.dev feedback:

https://sashiko.dev/#/patchset/6000262.DvuYhMxLoT%40rafael.j.wysocki

Patch [1/4] adds a NULL pointer check to prevent a possible NULL pointer
dereference from occurring.

Patch [2/4] fixes issues related to acpi_nfit_init() failures.

Patch [3/4] is a preparatory cleanup before the next patch.

Patch [4/4] addresses a possible deadlock during driver removal or
failing probe and missing NVDIMM device notifications from platform
firmware.

Thanks!
