[ Upstream commit4a24efa16e] The driver overrides the error codes returned by platform_get_irq() to -EINVAL, so if it returns -EPROBE_DEFER, the driver would fail the probe permanently instead of the deferred probing. Switch to propagating the error code upstream, still checking/overriding IRQ0 as libata regards it as "no IRQ" (thus polling) anyway...

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.
