commitcc9ca4d958upstream. The Tegra serial driver always prints an error message when enabling the FIFO for devices that have support for checking the FIFO enable status. Fix this by displaying the error message, only when an error occurs. Finally, update the error message to make it clear that enabling the FIFO failed and display the error code.

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.
