Subject: [PATCH 06/16] of: overlay: do not duplicate properties from overlay for new nodes
Date: Thu, 4 Oct 2018 21:12:37 -0700 [thread overview]
Message-ID: <1538712767-30394-7-git-send-email-frowand.list@gmail.com> (raw)
In-Reply-To: <1538712767-30394-1-git-send-email-frowand.list@gmail.com>
From: Frank Rowand <frank.rowand@sony.com>
When allocating a new node, add_changeset_node() was duplicating the
properties from the respective node in the overlay instead of
allocating a node with no properties.
When this patch is applied the errors reported by the devictree
unittest from patch "of: overlay: add tests to validate kfrees from
overlay removal" will no longer occur. These error messages are of
the form:
"OF: ERROR: ..."
and the unittest results will change from:
### dt-test ### end of unittest - 203 passed, 7 failed
to
### dt-test ### end of unittest - 210 passed, 0 failed
