David Bauer 91629921ce spi: ath79: always call chipselect function 
[ Upstream commit 19e2132174583beb90c1bd3e9c842bc6d5c944d1 ]

spi-bitbang has to call the chipselect function on the ath79 SPI driver
in order to communicate with the SPI slave device, as the ath79 SPI
driver has three dedicated chipselect lines but can also be used with
GPIOs for the CS lines.

Fixes commit 4a07b8bcd5 ("spi: bitbang: Make chipselect callback optional")

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.
