[ Upstream commit 9c45f95222 ]
During raw read, neither the status of the ECC correction nor the erased
state of the codeword gets checked by the qcom_spi_read_cw_raw() function,
so in case of raw access reading the corresponding registers via DMA is
superfluous.
Extend the qcom_spi_config_cw_read() function to evaluate the existing
(but actually unused) 'use_ecc' parameter, and configure reading only
the flash status register when ECC is not used.
With the change, the code gets in line with the corresponding part of
the config_nand_cw_read() function in the qcom_nandc driver.

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 reStructuredText 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.
