Smatch complains that "dentry" is never initialized. These days everyone
initializes all their stack variables to zero so this means that it will
trigger a warning every time this function is run.
Really, debugfs functions are not supposed to be checked for errors in
normal code. For example, if we updated this code to check the correct
variable then it would print a warning if CONFIG_DEBUGFS was disabled. We
don't want that. Just delete the 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.
