Currently commit 1f682dc9fb ("ath11k: reduce the wait time of 11d scan
and hw scan while add interface") introduced a wait_for_completion_timeout
operation for ar->scan.completed, another one is existed in ath11k_scan_stop(),
then ath11k has two places to wait for the ar->scan.completed and they
run in different thread, thus it is possible to happend that the two
thread both enter wait status. To handle this scenario, ath11k should
change the complete() to complete_all() for the ar->scan.completed. This
also work well when it is only one thread wait for ar->scan.completed.

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.
