The sof-pci-dev driver fails to link when built into the kernel
and CONFIG_SND_INTEL_DSP_CONFIG is set to =m:
arm-linux-gnueabi-ld: sound/soc/sof/sof-pci-dev.o: in function `sof_pci_probe':
sof-pci-dev.c:(.text+0x1c): undefined reference to `snd_intel_dsp_driver_probe'
As a temporary fix, use IS_REACHABLE to prevent the problem from
happening. A more complete solution is to move this code to
Intel-specific parts, restructure the drivers and Kconfig as discussed
with Arnd Bergmann and Takashi Iwai.

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.
