There are cases where we would like to continue probing the switch even if one port has failed to probe. When that happens, we need to unregister a devlink_port of type DEVLINK_PORT_FLAVOUR_PHYSICAL and re-register it of type DEVLINK_PORT_FLAVOUR_UNUSED. This is fine, except when calling devlink_port_attrs_set on a structure on which devlink_port_register has been previously called, there is a WARN_ON in devlink_port_attrs_set that devlink_port->devlink must be NULL. So don't assume that the memory behind dlp is clean when calling ocelot_port_devlink_init, just zero-initialize it.

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.
