Rafael J. Wysocki e38f9ff63e ACPI: scan: Do not add device IDs from _CID if _HID is not valid
Section 6.1.2 of ACPI 6.4 explicitly requires _HID to be present for
_CID to be defined, so don't add device IDs from _CID to the device
IDs list of a device if _HID is not valid.

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.
