debugfs_get_tree() can only be called if debugfs itself calls simple_pin_fs() or register_filesystem(), and those call paths also check the access mode. debugfs_start_creating() checks the access mode so the checks in the debugfs_create_* functions are unnecessary. An upcoming change will affect debugfs_allow, so doing this cleanup first will make that change simpler.

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.
