Christoph Hellwig 0c884f3236 firmware: qcom_scm: fix bogous abuse of dma-direct internals 
[ Upstream commit 459b1f86f1 ]

As far as the device is concerned the dma address is the physical
address.  There is no need to convert it to a physical address,
especially not using dma-direct internals that are not available
to drivers and which will interact badly with IOMMUs.  Last but not
least the commit introducing it claimed to just fix a type issue,
but actually changed behavior.

Fixes: 6e37ccf78a ("firmware: qcom_scm: Use proper types for dma mappings")

README 

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.
