debugfs_create_xxx routines, which return pointers, are being checked for
error by looking for NULL values. The routines may return pointer-munged
-Exxx codes, so they should be using IS_ERR() to adapt.
There are two cases:
- The first case is on initial directory creation, which actually doesn't
need to be checked. So remove the check.
- Creation of the sessions subdirectory. Modify this creation to create
under the initial directory created, and fix failure check.

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.
