soundwire: slave: fix an OF node reference leak in soundwire slave device
[ Upstream commit aac2f8363f773ae1f65aab140e06e2084ac6b787 ]
When initializing a soundwire slave device, an OF node is stored to the
device with refcount incremented. However, the refcount is not
decremented in .release(), thus call of_node_put() in
sdw_slave_release().
