 setup_of() now ensures that of_root node is populated with the
 root of a default devicetree. Remove the unittest code that
 created of_root if it was missing.  Verify that of_root is
 valid before attempting to attach the testcase-data subtree.

What happened with the formatting here?

I'm guessing you are referring to the leading space?

I pasted the text from another file into the commit message in
my repo and failed to remove the leading blank. So a "typo"
on my part.
