The ice_ptp_link_change function is currently only called for E822 based hardware. Future changes are going to extend this function to perform additional tasks on link change. Always call this function, moving the E810 check from the callers down to just before we call the E822-specific function required to restart the PHY. This function also returns an error value, but none of the callers actually check it. In general, the errors it produces are more likely systemic problems such as invalid or corrupt port numbers. No caller checks these, and so no warning is logged. Re-order the flag checks so that ICE_FLAG_PTP is checked first. Drop the unnecessary check for ICE_FLAG_PTP_SUPPORTED, as ICE_FLAG_PTP will not be set except when ICE_FLAG_PTP_SUPPORTED is set. Convert the port checks to WARN_ON_ONCE, in order to generate a kernel stack trace when they are hit. Convert the function to void since no caller actually checks these return values.

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.
