[ Upstream commita129950516] When adding the code to handle platform_get_irq*() errors in the commit489447380a("handle errors returned by platform_get_irq*()"), the actual error code was enforced to be -ENXIO in the driver for some strange reason. This didn't matter much until the deferred probing was introduced -- which requires an actual error code to be propagated upstream from the failure site. While fixing this, also stop overriding the errors from request_irq() to -EIO (done since the pre-git era).

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.
