All the queue management code runs under mvm->mutex, so there are only very few cases of accessing the data structures without it: * TX path, which doesn't take any locks anyway * iwl_mvm_wake_sw_queue() and iwl_mvm_stop_sw_queue() where we just (atomically) read a bitmap, so the lock isn't needed. Therefore, we can remove the spinlock. This enables some cleanup in the ugly locking in iwl_mvm_inactivity_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.
