tcs_is_free() had two checks in it: does the software think that the TCS is free and does the hardware think that the TCS is free. I couldn't figure out in which case the hardware could think that a TCS was in-use but software thought it was free. Apparently there is no case and the extra check can be removed. This apparently has already been done in a downstream patch.

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.
