From e984fd61e860ce3c45e79d69cf214b8cc6cae7d9 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 23 Jan 2017 07:29:42 +0000 Subject: [PATCH] ASoC: simple-card: use devm_get_clk_from_child() Current simple-card-utils is getting clk by of_clk_get(), but didn't call clk_free(). Now we can use devm_get_clk_from_child() for this purpose. Let's use it.
