commit c08934a61201db8f1d1c66fcc63fb2eb526b656d upstream. Make sure to drop the reference taken to the iommu platform device when looking up its driver data during probe_device(). Note that commit9826e393e4("iommu/tegra-smmu: Fix missing put_device() call in tegra_smmu_find") fixed the leak in an error path, 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.
