Wei Yongjun 0e54705b0e irqchip/exiu: Fix return value check in exiu_init()
In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR().

Replace the IS_ERR() test of the return value with NULL test and return
a proper error code.

Fixes: 706cffc1b9 ("irqchip/exiu: Add support for Socionext Synquacer EXIU controller")

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
