Guenter Roeck 094e8f78c6 of: Skip devicetree kunit tests when RISCV+ACPI doesn't populate root node 
[ Upstream commit 546dbb0223 ]

Starting with commit 69a8b62a7a ("riscv: acpi: avoid errors caused by
probing DT devices when ACPI is used"), riscv images no longer populate
devicetree if ACPI is enabled. This causes unit tests to fail which require
the root node to be set.

  # Subtest: of_dtb
  # module: of_test
  1..2
  # of_dtb_root_node_found_by_path: EXPECTATION FAILED at drivers/of/of_test.c:21
  Expected np is not null, but is
  # of_dtb_root_node_found_by_path: pass:0 fail:1 skip:0 total:1
  not ok 1 of_dtb_root_node_found_by_path
  # of_dtb_root_node_populates_of_root: EXPECTATION FAILED at drivers/of/of_test.c:31
  Expected of_root is not null, but is
  # of_dtb_root_node_populates_of_root: pass:0 fail:1 skip:0 total:1
  not ok 2 of_dtb_root_node_populates_of_root

Skip those tests for RISCV if the root node is not populated.

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 reStructuredText 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.
