From: Zijun Hu <quic_zijuhu@quicinc.com>

tps23881_get_of_channels() invokes of_find_node_by_name(@priv->np, ...)
and the callee will put OF device node @priv->np refcount, but the caller
does not compensate the refcount before the invocation, so causes the node
refcount leakage.

Fix by of_node_get(@priv->np) before the invocation.
