[ Upstream commitacd194d9b5] The driver calls ioport_map() to map I/O ports in sim710_probe_common() but never calls ioport_unmap() to release the mapping. This causes resource leaks in both the error path when request_irq() fails and in the normal device removal path via sim710_device_remove(). Add ioport_unmap() calls in the out_release error path and in sim710_device_remove().

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.
