SND_SOC_SDCA can't be optional when SND_SOC_ACPI_INTEL_SDCA_QUIRKS is selected. IS_REACHABLE can prevent the link error. However it is not suitable for this case. When CONFIG_SND_SOC_ACPI_INTEL_SDCA_QUIRKS is Y and CONFIG_SND_SOC_SDCA is M, the SDCA helpers will be empty and return false. But we need the helpers to do their jobs whenSND_SOC_SDCA is M. IOW, the SDCA library is not optional for Intel platforms where the SDCA_QUIRK is selected. Also, make SND_SOC_SDCA invisible. SND_SOC_SDCA should be selected if a device supports SDCA. User should not unselect it.

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 reStructuredText 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.
