Subject: [PATCH 4.14 054/136] clk: ti: composite: fix memory leak

From: Tero Kristo <t-kristo@...com>

[ Upstream commit c7c1cbbc9217ebb5601b88d138d4a5358548de9d ]

The parent_names is never released for a component clock definition,
causing some memory leak. Fix by releasing it once it is no longer
needed.
