Benjamin Berg e83bc93886 wifi: mac80211: take lock before setting vif links
[ Upstream commit 15846f95ab ]

ieee80211_vif_set_links requires the sdata->local->mtx lock to be held.
Add the appropriate locking around the calls in both the link add and
remove handlers.

This causes a warning when e.g. ieee80211_link_release_channel is called
via ieee80211_link_stop from ieee80211_vif_update_links.

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.
