[PATCH 3/5] of: unittest: kmemleak in of_unittest_overlay_high_level()
From: frowand . list
Date: Thu Apr 16 2020 - 17:45:02 EST
From: Frank Rowand <frank.rowand@xxxxxxxx>
kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 3 of 5.
of_unittest_overlay_high_level() failed to kfree the newly created
property when the property named 'name' is skipped.
Fixes: 39a751a4cb7e ("of: change overlay apply input data from unflattened to FDT")
Reported-by: Erhard F. <erhard_f@xxxxxxxxxxx>
