The liquidio driver is broken by design. It initialize PCI devices in separate delayed works. It causes to the situation where device lock is dropped during initialize and remove sequences. That lock is part of driver/core and needed to protect from races during init, destroy and bus invocations. In addition to lack of locking protection, it has incorrect order of destroy flows and very questionable synchronization scheme based on atomic_t. This change doesn't fix that driver but makes sure that rest of the netdev subsystem doesn't suffer from such basic protection by adding device_lock over devlink_*() APIs and by moving devlink_register() to be last command in setup_nic_devices().

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.
