The IS_ERR_OR_NULL check for priv->fdvfs is inappropriate, and should be
an IS_ERR check instead, as a NULL value here would propagate it to
PTR_ERR.
In practice, there is no problem here, as devm_of_iomap cannot return
NULL in any circumstance. However, it causes a Smatch static checker
warning.
Fix the warning by changing the check from IS_ERR_OR_NULL to IS_ERR.

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.
