[ Upstream commit b6052c3c7a78f5e2b9756c92ef77c0b56435f107 ]
If an error occurs after a successful 'of_iomap()' call, it must be undone
by a corresponding 'iounmap()' call, as already done in the remove
function.
While at it, remove the useless initialization of 'ret' at the beginning of
the function.

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.
