Clear the error flags after disabling the module to avoid the case when a flag is set again between flag clear and module disable. And use SR_CLEAR_MASK to replace hardcoded value for improved readability. Although fsl_lpspi_reset() was only introduced in commita15dc3d657("spi: lpspi: Fix CLK pin becomes low before one transfer"), the original driver only reset SR in the interrupt handler, making it vulnerable to the same issue. Therefore the fixes commit is set at the introduction of the driver.

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.
