[ Upstream commit6dbaa4d288] sh_msiof_spi_reset_regs() asserts TX/RX reset and polls until the reset bits clear, but the poll result is ignored. sh_msiof_transfer_one() can therefore continue programming a transfer after the controller did not leave reset. Return the reset poll result from the helper and abort the transfer on timeout, matching the existing transfer path's error-return style.

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.
