Commit 76c47d1449fc ("gpio: mpc8xxx: Add ACPI support") has switched to a
managed version when dealing with 'mpc8xxx_gc->regs'. So the corresponding
'iounmap()' call in the error handling path and in the remove should be
removed to avoid a double unmap.
This also allows some simplification in the probe. All the error handling
paths related to managed resources can be direct returns and a NULL check
in what remains in the error handling path can be removed.

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.
