From 40e3b847bff70edc28c5290d209e531da6f9e534 Mon Sep 17 00:00:00 2001
From: Christian Lamparter <chunkeey@googlemail.com>

Subject: [PATCH 10/25] crypto: crypto4xx - replace crypto4xx_dev's
scatter_buffer_size with constant
scatter_buffer_size is always set to PPC4XX_SD_BUFFER_SIZE.
I don't think there's any point in keeping the variable
around.
