The helper is explicitly documented as locking zero, one, or two
arguments. While all current callers do pass non-NULL arguments there's
no need or requirement for them to do so according to the code and the
unlock_two_nondirectories() helper is pretty clear about it as well. So
only call WARN_ON_ONCE() if the checked inode is valid.
Fixes: 2454ad83b9 ("fs: Restrict lock_two_nondirectories() to non-directory inodes")

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.
