Subject: [patch 1/2] drm/exynos: mic: fix an error code
Date: Thu, 17 Mar 2016 13:32:15 +0300	[thread overview]
Message-ID: <20160317103214.GA3100@mwanda> (raw)

We accidentally return success instead of a negative error code here.

This is the common problem introduced by do nothing gotos.  The other
issue with do nothing gotos is that they are annoying and don't actually
prevent people from putting a direct return in the middle of functions.
