Let's update the changelog to be helpful for someone implementing a
backport or taking this back to a -stable branch.  Something like:

Subject: acpi, nfit: fix event notifications

Commit 209851649dc4 "acpi: nfit: Add support for hot-add" added
support for _FIT notifications, but it neglected to set the
ACPI_DRIVER_ALL_NOTIFY_EVENTS flag that acpi_bus_notify() uses to gate
notification delivery.

Fixes: 209851649dc4 ("acpi: nfit: Add support for hot-add")
