The lock can be extended a bit to protect other elements that are not particular to just TX/RX. Another idea would have been to just add a new `state_lock`, but that would mean 2 locks which would be redundant, and probably cause more potential for dead-locks. What will be done in the next patches, will be to add some unlocked versions for read/write_reg functions.

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.
