It's a good practice to disable all IRQs if a device is fully unused. In our case it is supposed to be done before requesting the IRQ and after the last byte of an SPI transfer is received. In the former case it's required to prevent the IRQ handler invocation before the driver data is fully initialized (which may happen if the IRQs status has been left uncleared before the device is probed). So we just moved the spi_hw_init() method invocation to the earlier stage before requesting the IRQ. In the later case there is just no point in having any of the IRQs enabled between SPI transfers and when there is no SPI message currently being processed.

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.
