Queue spinlock is currently held in mtk_wed_wo_queue_rx_clean and mtk_wed_wo_queue_refill routines for MTK Wireless Ethernet Dispatcher MCU rx queue. mtk_wed_wo_queue_refill() is running during initialization and in rx tasklet while mtk_wed_wo_queue_rx_clean() is running in mtk_wed_wo_hw_deinit() during hw de-init phase after rx tasklet has been disabled. Since mtk_wed_wo_queue_rx_clean and mtk_wed_wo_queue_refill routines can't run concurrently get rid of spinlock for mcu rx queue.

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.
