There are two callers of file_lookup(), but there is no more reason
to expand the given path.
[1] zconf_initscan()
This is used to open the first Kconfig. sym_expand_string_value()
has never been used in a useful way here; before opening the first
Kconfig file, obviously there is no symbol to expand. If you use
expand_string_value() instead, environments in KBUILD_KCONFIG would
be expanded, but I do not see practical benefits for that.
[2] zconf_nextfile()
This is used to open the next file from 'source' statement.
Symbols in the path like "arch/$SRCARCH/Kconfig" needed expanding,
but it was replaced with the direct environment expansion. The
environment has already been expanded before the token is passed
to the parser.
By the way, file_lookup() was already buggy; it expanded a given path,
but it used the path before expansion for look-up:
if (!strcmp(name, file->name)) {

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
