CONFIG_INTEL_MEI_VSC_HW can be set to built-in even with CONFIG_MEI=m,
but then the driver is not built because Kbuild never enters the
drivers/misc/mei directory for built-in files, leading to a link
failure:

ERROR: modpost: "vsc_tp_init" [drivers/misc/mei/mei-vsc.ko] undefined!

ERROR: modpost: "vsc_tp_register_event_cb" [drivers/misc/mei/mei-vsc.ko] undefined!
Add an explicit dependency on CONFIG_MEI that was apparently missing,
to ensure the VSC_HW driver cannot be built-in with MEI itself being
a loadable module.

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.
