[PATCH 00/13] of: overlay/unittest: Miscellaneous fixes and improvements

[Geert Uytterhoeven <geert+renesas@glider.be>]

	Hi all,

This patch series contains miscellaneous fixes and improvements for
dynamic DT overlays and the related unit tests.

The first two patches are fixes for a lock-up and a crash.
The remaining patches are smaller fixes, enhancements and cleanups for
the overlay tests, including one new test.

I ran into the crash when accidentally loading the wrong overlay (using
the out-of-tree DT overlay configfs[1]), and removing it afterwards.
As this case was not yet covered by the unittests, I added a test.
I enhanced the tests to clean up partial state after a failed
overlay apply attempt, which triggered the lock-up.

Thanks for your comments!
