During second CT initialization step, known as post_hwconfig, we want to replace previously registered CT disable devm action to make sure it will be invoked prior to releasing underlying BO. But to replace this action we don't need to execute it right away since we know that CT was disabled prior to that late init step and we already assert that. Use devm_remove_action() instead to avoid extra message about 'disabling CT' that could be seen now: [drm:guc_ct_change_state [xe]] GT0: GuC CT communication channel disabled ...

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 reStructuredText 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.
