[ Upstream commit18b3af4492] A change made in the final version of IOMMU debugfs support replaced the public function iommu_debugfs_new_driver_dir() by the public dentry iommu_debugfs_dir in <linux/iommu.h>, but forgot to update both the implementation in iommu-debugfs.c, and the patch description. Fix this by exporting iommu_debugfs_dir, and removing the reference to and implementation of iommu_debugfs_new_driver_dir().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
