We should only try to execute fallback quirks handling when previous
call returned -ENOENT, and not when we did not get -EPROBE_DEFER.
The other errors should be treated as hard errors: we did find the GPIO
description, but for some reason we failed to handle it properly.
The fallbacks should only be executed when previous handlers returned
-ENOENT, which means the mapping/description was not found.
Also let's remove the explicit deferral handling when iterating through
GPIO suffixes: it is not needed anymore as we will not be calling
fallbacks for anything but -ENOENT.

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.
