Since commite89f45edb7("ASoC: amd: vangogh: Add check for acp config flags in vangogh platform"), the Vangogh ACP PCI driver could not be used anymore for boards which happen to have a matching entry in acp-config list. Commitf18818eb0d("ASoC: amd: vangogh: Add condition check for acp config flag") slightly changed the behaviour to permit loading the driver if AMD_LEGACY flag is set. However, for AMD_SOF flag the probing is still denied, even if SOF support is disabled in kernel configuration. While this helps preventing conflicts between SOF and generic ACP drivers, there are cases where a fallback to the generic non-SOF support would still be needed or useful, e.g. SOF firmware is not available or doesn't work properly, SOF driver is broken or doesn't provide full support for a particular hardware, or simply for testing/debugging the alternative solution. A real-life example is Steam Deck OLED, which works with both drivers. Prevent returning from probe() when ACP config indicates SOF support for the current board *and* the Vangogh SOF driver is not enabled in kernel configuration.

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.
