[ Upstream commitc202e2ebe1] This error path leads to a Smatch warning: drivers/net/wireless/ath/ath11k/mac.c:4269 ath11k_mac_op_start() error: double unlocked '&ar->conf_mutex' (orig line 4251) We're not holding the lock when we do the "goto err;" so it leads to a double unlock. The fix is to hold the lock for a little longer.

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.
