Subject: [PATCH 2/3] mtd/nand : set correct length to FBCR for a non-full-page write
Date: Sun, 4 Dec 2011 12:31:37 +0800	[thread overview]
Message-ID: <1322973098-2528-2-git-send-email-shuo.liu@freescale.com> (raw)
In-Reply-To: <1322973098-2528-1-git-send-email-shuo.liu@freescale.com>

From: Liu Shuo <b35362@freescale.com>

When we do a non-full-page write, the length be set to FBCR should
not be 'elbc_fcm_ctrl->index', it should be 'elbc_fcm_ctrl->index -
elbc_fcm_ctrl->column'.
