If register_netdev() fails, the driver will attempt to cleanup the q_vectors and inadvertently trigger a kernel BUG due to a NULL pointer dereference. This occurs because cleaning up q_vectors attempts to call netif_napi_del on napi_structs which were never initialized. Resolve this by releasing the netdev in ice_cfg_netdev and setting vsi->netdev to NULL. This ensures that after ice_cfg_netdev fails the state is rewound to match as if ice_cfg_netdev was never called.

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.
