Refering to platform_get_irq()'s definition, the return value has already been checked if ret < 0, and printed via dev_err_probe(). Calling dev_err_probe() one more time outside platform_get_irq() is obviously redundant. Furthermore, platform_get_irq() will never return irq equals 0, removing spi->irq == 0 checking to clean it up.

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.
