[ Upstream commit75dce6a941] wait_for_completion_timeout() and readl_poll_timeout() don't handle their return value the same way. wait_for_completion_timeout() returns 0 on time out (and >0 in all other cases) readl_poll_timeout() returns 0 on success and -ETIMEDOUT upon a timeout. In order for the error handling path to work in both cases, the logic against wait_for_completion_timeout() needs to be inverted.

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.
