Arnd Bergmann aa767cfb75 of: provide inline helper for of_find_device_by_node
The ipmmu-vmsa driver fails in compile-testing on non-OF platforms:

drivers/iommu/ipmmu-vmsa.o: In function `ipmmu_of_xlate':
ipmmu-vmsa.c:(.text+0x740): undefined reference to `of_find_device_by_node'

It would be reasonable to assume that this interface works but
returns failure on non-OF builds, like it does on machines that
have been booted in another way, so this adds another inline
function helper.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
