From 3c436bf95a1df22fa501be7134bccd29f8387dfe Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 28 Dec 2015 19:23:02 +0900 Subject: [PATCH] clk: drop the initial core->parents look-ups from __clk_core_init() The core->parents is a cache to save expensive clock parent look-ups. It will be filled as needed later. We do not have to do it here.
