Subject: [PATCH 2/7] mtd: onenand: drop dead code
Date: Sat, 28 Feb 2015 02:02:25 -0800	[thread overview]
Message-ID: <1425117750-22298-3-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1425117750-22298-1-git-send-email-computersforpeace@gmail.com>

'ret' is always zero, so this is all dead code.

This should quiet Coverity CID #1226739.
