On start of rtllib_wx_set_scan lock was taken with mutex_lock(&ieee->wx_mutex). Unlocking was done at the end of schedule_work(&ieee->wx_sync_scan_wq) which lead to the error "lock held when returning to user space!". Pushing lock to beginning of ieee->wx_sync_scan_wq to improve overview. Removed lock from rtllib_wx_set_scan as ieee->state, ieee->iw_mode and ieee->proto_started are not protected in many other places.

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.
