The function wfx_tx_flush() wait for there is no more queued frames in hardware queue. Then, for the sanity, it checks that there is no more pending frame on any AC queue. However, there is a race here. It may happens that hardware queues are empty, but the counters of the AC queues are not yet updated. So, it may produce false-positive warning. The easiest way to solve the problem is just to remove the sanity check.

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.
