QCOM IOMMU driver calls bus_set_iommu() for every IOMMU device controller, what fails for the second and latter IOMMU devices. This is intended and must be not fatal to the driver registration process. Also the cleanup path should take care of the runtime PM state, what is missing in the current patch. Revert relevant changes to the QCOM IOMMU driver until a proper fix is prepared. This partially reverts commit249c9dc6aa.

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.
