[ Upstream commit f5297a01ee805d7fa569d288ed65fc0f9ac9b03d ] "pcie_retrain_link" is not a question with a true/false answer, so "bool" isn't quite the right return type. Return 0 for success or -ETIMEDOUT if the retrain failed. No functional change intended.

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.
