Praveenkumar I 392a56b9f2 mtd: rawnand: qcom: Fix DMA sync on FLASH_STATUS register read 
commit bc36860211 upstream.

After each codeword NAND_FLASH_STATUS is read for possible operational
failures. But there is no DMA sync for CPU operation before reading it
and this leads to incorrect or older copy of DMA buffer in reg_read_buf.

This patch adds the DMA sync on reg_read_buf for CPU before reading it.

Fixes: 5bc36b2bf6 ("mtd: rawnand: qcom: check for operation errors in case of raw read")

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.
