Make ibm_init_struct.init() callbacks return -ENODEV instead of 1 when the subdevice / function is not available. Using -ENODEV clearly states what it going on where as a magic return of "1" requires a deep dive into the code to figure out what is going on. This also allows for some cleanups, avoiding the need to translate an -ENODEV return into "return 1" (which often mistakenly was "return 0").

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.
