Ryzen 7000 (Raphael) introduced AMDI0008 for _HID. This ID was added in commited470febf8("ACPI: PM: s2idle: Add support for upcoming AMD uPEP HID AMDI008"), but then removed in favor of aligning all new IDs to Rembrandt support in commitfd894f05cf("ACPI: x86: s2idle: If a new AMD _HID is missing assume Rembrandt"). Unfortunately there was a mistake in commit100a573793("ACPI: x86: s2idle: Move _HID handling for AMD systems into structures") that can lead to a NULL pointer dereference accessing `dev_id->driver_data` in the sentinel of `amd_hid_ids`. Fix this dereference.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
