[PATCH 5.4 018/118] of: overlay: kmemleak in dup_and_fixup_symbol_prop()

[Greg Kroah-Hartman]

From: Frank Rowand <frank.rowand@xxxxxxxx>

commit 478ff649b1c8eb2409b1a54fb75eb46f7c29f140 upstream.

kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 4 of 5.

target_path was not freed in the non-error path.
