dpaa2_mac_disconnect() will only be called with a NULL mac->phylink if dpaa2_mac_connect() failed, or was never called. The callers are these: dpaa2_eth_disconnect_mac(): if (dpaa2_eth_is_type_phy(priv)) dpaa2_mac_disconnect(priv->mac); dpaa2_switch_port_disconnect_mac(): if (dpaa2_switch_port_is_type_phy(port_priv)) dpaa2_mac_disconnect(port_priv->mac); priv->mac can be NULL, but in that case, dpaa2_eth_is_type_phy() returns false, and dpaa2_mac_disconnect() is never called. Similar for dpaa2-switch. When priv->mac is non-NULL, it means that dpaa2_mac_connect() returned zero (success), and therefore, priv->mac->phylink is also a valid pointer.

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.
