Subject: [PATCH 01/11] ASoC: samsung: s3c2412: Handle return value of clk_prepare_enable.
Date: Tue, 25 Jul 2017 15:44:28 +0530	[thread overview]
Message-ID: <1500977674-27960-2-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1500977674-27960-1-git-send-email-arvind.yadav.cs@gmail.com>

clk_prepare_enable() can fail here and we must check its return value.
