commit 05913cc43cb122f9afecdbe775115c058b906e1b upstream. Make sure to drop the reference taken to the iommu platform device when looking up its driver data during of_xlate(). Note that commit1a26044954("iommu/exynos: add missing put_device() call in exynos_iommu_of_xlate()") fixed the leak in a couple of error paths, but the reference is still leaking on success.

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.
