Subject: [PATCH 2/3] ASoC: simple-card: use devm_get_clk_from_child()
Date: Mon, 5 Dec 2016 05:23:37 +0000 [thread overview]
Message-ID: <871sxnvtkp.wl%kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <874m2jvtmw.wl%kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
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.
