This will allow the low level driver to get the wdev during the add_interface flow. In order to do that, remove a few checks from there and do not return NULL for vifs that were not yet added to the driver. Note that all the current callers of this helper function assume that the vif already exists: - The callers from the drivers already have a vif pointer. Before this change, ieee80211_vif_to_wdev would return NULL in some cases, but those callers don't even check they get a non-NULL pointer from ieee80211_vif_to_wdev. - The callers from net/mac80211/cfg.c assume the vif is already added to the driver as well. So, this change has no impact on existing callers of this helper function.

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.
