macb_ptp_desc will not return NULL under most circumstances with correct Kconfig and IP design config register. But for the sake of the extreme corner case, check for NULL when using the helper. In case of rx_tstamp, no action is necessary except to return (similar to timestamp disabled) and warn. In case of TX, return -EINVAL to let the skb be free. Perform this check before marking skb in progress.

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.
