If the PCI connection is broken, reading the FW version string will only get 0xff bytes, which shouldn't get printed. This checks the first byte and prints only the first 4 bytes if non-ASCII. Also, add a limit to the string length printed when a valid string is found, just in case it is not properly terminated. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

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.
