Currently uninit is sometimes done twice in error flows, and is sprinkled a bit all over the place. Improve the clarity of the design by moving all uninit only into ndo_uinit. Some duplication is removed: - Sometimes IPOIB_STOP_NEIGH_GC was done before unregister, but this duplicates the process in ipoib_neigh_hash_init - Flushing priv->wq was sometimes done before unregister, but that duplicates what has been done in ndo_uninit Uniniting the IB event queue must remain before unregister_netdev as it requires the RTNL lock to be dropped, this is moved to a helper to make that flow really clear and remove some duplication in error flows. If register_netdev fails (and ndo_init is NULL) then it almost always calls ndo_uninit, which lets us remove all the extra code from the error unwinds. The next patch in the series will close the 'almost always' hole by pairing a proper ndo_init with ndo_uninit.

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
