Subject: [PATCH 0/5] of: unittest: kmleak detected memory leaks

From: Frank Rowand <frank.rowand@...y.com>

Original bug report:
  https://bugzilla.kernel.org/show_bug.cgi?id=206203
  https://lore.kernel.org/r/877dyqlles.fsf@mpe.ellerman.id.au

kmemleak detected many memory leaks originating if devicetree
unittests.

Five separate causes were found.  Four causes were bugs and
one was expected.

Fix the four bugs and modify the test that led to the expected
memory leak to no longer have a memory leak.
