Subject: [PATCH 017/102] ASoC: sta32x: Fix array access overflow
Date: Tue, 18 Feb 2014 12:36:52 +0100	[thread overview]
Message-ID: <1392723422-12689-2-git-send-email-tiwai@suse.de> (raw)
In-Reply-To: <1392723422-12689-1-git-send-email-tiwai@suse.de>

Preset EQ enum of sta32x codec driver declares too many number of
items and it may lead to the access over the actual array size.

Use SOC_ENUM_SINGLE_DECL() helper and it's automatically fixed.
