Larisa Grigore cd53048e74 spi: spi-fsl-lpspi: Reset FIFO and disable module on transfer abort 
[ Upstream commit e811b088a3 ]

In DMA mode fsl_lpspi_reset() is always called at the end, even when the
transfer is aborted. In PIO mode aborts skip the reset leaving the FIFO
filled and the module enabled.

Fix it by always calling fsl_lpspi_reset().

Fixes: a15dc3d657 ("spi: lpspi: Fix CLK pin becomes low before one transfer")

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.
