Refactor dspi_rxtx() and dspi_poll() to not return -EINPROGRESS because this isn't actually a status that is ever returned to the core layer but some internal state. Use true/false return value on dspi_rxtx() for this instead. This will help separate internal vs external status for the later change to store the external status directly in cur_msg->status. No functional changes intended.

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.
