The snd-amd-sdw-acpi.ko module is under CONFIG_SND_SOC_AMD_ACP_COMMON but selected from SoF, which causes build failures in some randconfig builds that enable SOF but not ACP: WARNING: unmet direct dependencies detected for SND_AMD_SOUNDWIRE_ACPI Depends on [n]: SOUND [=m] && SND [=m] && SND_SOC [=m] && SND_SOC_AMD_ACP_COMMON [=n] && ACPI [=y] Selected by [m]: - SND_SOC_SOF_AMD_SOUNDWIRE_LINK_BASELINE [=m] && SOUND [=m] && SND [=m] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_AMD_TOPLEVEL [=m] && ACPI [=y] ERROR: modpost: "amd_sdw_scan_controller" [sound/soc/sof/amd/snd-sof-amd-acp.ko] undefined!

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.
