Flushing system-wide workqueues is dangerous and will be forbidden. Replace system_wq with local wwan_wq. While we are at it, make err_clean_devs: label of wwan_hwsim_init() behave like wwan_hwsim_exit(), for it is theoretically possible to call wwan_hwsim_debugfs_devcreate_write()/wwan_hwsim_debugfs_devdestroy_write() by the moment wwan_hwsim_init_devs() returns.

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.
