Subject: [PATCH v3 10/10] mtd: pxa3xx_nand: utilize oob_required parameter
Date: Fri, 27 Apr 2012 18:29:54 -0700	[thread overview]
Message-ID: <1335576594-25267-11-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1335576594-25267-1-git-send-email-computersforpeace@gmail.com>

Don't read/write OOB if the caller doesn't require it.
