Daniel Scally bf263f64e8 media: ACPI / bus: Add acpi_dev_get_next_match_dev() and helper macro
To ensure we handle situations in which multiple sensors of the same
model (and therefore _HID) are present in a system, we need to be able
to iterate over devices matching a known _HID but unknown _UID and _HRV
 - add acpi_dev_get_next_match_dev() to accommodate that possibility and
change acpi_dev_get_first_match_dev() to simply call the new function
with a NULL starting point. Add an iterator macro for convenience.

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.
