The rtwdev->rf_lock spinlock protects the rf register accesses in rtw_read_rf() and rtw_write_rf(). Most callers of these functions hold rtwdev->mutex already with the exception of the callsites in the debugfs code. The debugfs code doesn't justify an extra lock, so acquire the mutex there as well before calling rf register accessors and drop the now unnecessary spinlock.

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.
