Greg KH suggests that normal code should not care about debugfs. Therefore no matter successful or failed of debugfs_create_dir() execution, it is unncessary to check its return value. There are two functions called debugfs_create_dir() and check the return value, which are bch_debug_init() and closure_debug_init(). This patch changes these two functions from int to void type, and ignore return values of debugfs_create_dir(). This patch does not fix exact bug, just makes things work as they should.

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.
