It's pretty possible to have the spi_register_controller() method returning -EPROBE_DEFER status in case, for instance, if the GPIOs used for the CS implementation aren't ready to be requested due to the corresponding platform devices still pending to be probed. Let's make sure the DW SSI driver won't print error message in that case by calling the dev_err_probe() function if the SPI-registration procedure exited with a non-zero status.

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.
