Subject: [PATCH v3 01/10] software node: Get reference to parent swnode in get_parent op
Date: Thu, 29 Aug 2019 13:10:34 +0300 [thread overview]
Message-ID: <20190829101043.24963-2-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20190829101043.24963-1-sakari.ailus@linux.intel.com>
The software_node_get_parent() returned a pointer to the parent swnode,
but did not take a reference to it, leading the caller to put a reference
that was not taken. Take that reference now.
Fixes: 59abd83672f7 ("drivers: base: Introducing software nodes to the
firmware node framework")
