tl;dr: Clean up an unnecessary export and enable cxl_test. An RCD (Restricted CXL Device), in contrast to a typical CXL device in a VH topology, obtains its component registers from the bottom half of the associated CXL host bridge RCRB (Root Complex Register Block). In turn this means that cxl_rcrb_to_component() needs to be called from devm_cxl_add_endpoint(). Presently devm_cxl_add_endpoint() is part of the CXL core, but the only user is the CXL mem module. Move it from cxl_core to cxl_mem to not only get rid of an unnecessary export, but to also enable its call out to cxl_rcrb_to_component(), in a subsequent patch, to be mocked by cxl_test. Recall that cxl_test can only mock exported symbols, and since cxl_rcrb_to_component() is itself inside the core, all callers must be outside of cxl_core to allow cxl_test to mock it.

README
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.
