In spi_mem_exec_op(), in case cs_gpiod descriptor is set, exec_op() callback can't be used. The same must be applied in spi_mem_poll_status(), poll_status() callback can't be used, we must use the legacy path using read_poll_timeout(). Tested on STM32mp257c-ev1 specific evaluation board on which a spi-nand was mounted instead of a spi-nor.

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.
