The -EEXIST conversion is introduced in commit65462462ff("mm/gup: follow_pfn_pte(): -EEXIST cleanup"), since follow_page() may call follow_pfn_pte() which may return -EEXIST. But after commit7dff875c94("mm/migrate: convert add_page_for_migration() from follow_page() to folio_walk"), it use folio_walk instead. This limit the error code and won't return -EEXIST. Remove the error code conversion here.

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.
