Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>: The PCI device registers contain a subsystem ID (SSID), that is separate from the silicon ID. The PCI specification defines it thus: "They provide a mechanism for board vendors to distiguish their boards from one another even thought the boards may have the same PCI controller on them." This allows the driver for the silicon part to apply board-speficic settings based on this SSID. The CS35L56 driver uses this to select the correct firmware file for the board. The actual ID is part of the PCI register set of the host audio interface so this set of patches includes extracting the SSID from the Intel audio controller and passing it to the machine driver and then to ASoC components. Other PCI audio controllers will have the same SSID registers, so can use the same mechanism to pass the SSID. |

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.
