The wil6210 driver locks a mutex in begin() ethtool_ops callback and unlocks it in complete() so that all ethtool requests are serialized. This is not going to work correctly with netlink interface; e.g. when ioctl triggers a netlink notification, netlink code would call begin() again while the mutex taken by ioctl code is still held by the same task. Let's get rid of the begin() and complete() callbacks and move the mutex locking into the remaining ethtool_ops handlers except get_drvinfo which only copies strings that are not changing so that there is no need for serialization.

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.
