david regan ffe36e3a99 mtd: rawnand: brcmnand: Fixed incorrect sub-page ECC status 
commit 36415a7964 upstream.

The brcmnand driver contains a bug in which if a page (example 2k byte)
is read from the parallel/ONFI NAND and within that page a subpage (512
byte) has correctable errors which is followed by a subpage with
uncorrectable errors, the page read will return the wrong status of
correctable (as opposed to the actual status of uncorrectable.)

The bug is in function brcmnand_read_by_pio where there is a check for
uncorrectable bits which will be preempted if a previous status for
correctable bits is detected.

The fix is to stop checking for bad bits only if we already have a bad
bits status.

Fixes: 27c5b17cd1 ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller")

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.
