commit b5870691065e6bbe6ba0650c0412636c6a239c5a upstream. Make sure to drop the references taken to the iommu platform devices when looking up their driver data during probe_device(). Note that the arch data device pointer added by commit604629bcb5("iommu/omap: add support for late attachment of iommu devices") has never been used. Remove it to underline that the references are not needed.

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.
