Jiasheng Jiang 9acf7c2f31 ray_cs: Check ioremap return value
[ Upstream commit 7e47607133 ]

As the possible failure of the ioremap(), the 'local->sram' and other
two could be NULL.
Therefore it should be better to check it in order to avoid the later
dev_dbg.

README

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.
