Wentao Liang bfbbef7f1d mtd: rawnand: Add status chack in r852_ready() 
commit b79fe18299 upstream.

In r852_ready(), the dev get from r852_get_dev() need to be checked.
An unstable device should not be ready. A proper implementation can
be found in r852_read_byte(). Add a status check and return 0 when it is
unstable.

Fixes: 50a487e771 ("mtd: rawnand: Pass a nand_chip object to chip->dev_ready()")

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.
