Jiasheng Jiang a14cb30726 pstore/ram: Add check for kstrdup 
[ Upstream commit d97038d5ec2062733c1e016caf9baaf68cf64ea1 ]

Add check for the return value of kstrdup() and return the error
if it fails in order to avoid NULL pointer dereference.

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.
