Automated tools complain that felix_check_xtr_pkt() has logic to drain the CPU queue on the reception of a PTP packet over Ethernet, yet it returns an uninitialized error code in the case where the CPU queue was empty. This is not likely to happen (/possible if hardware works correctly), but it isn't a fatal condition either. The PTP packet will be dequeued from the CPU queue when the next PTP packet arrives. So initialize "err" to 0 for the case where nothing was dequeued during this iteration.

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.
