When the third option (list) to ldebugfs_register() is NULL, it's the same as just calling debugfs_create_dir(). So unwind this and call debugfs_create_dir() directly. This ends up saving lots of code as we do not need to do any error checking of the return value (because it does not matter). The ldebugfs_register() call will be removed in a later patch when it is fully removed, right now there are 2 outstanding users of it in the tree.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
