linux-next: build failure after merge of the final tree

Hi David,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/mtd/nand/r852.c:22: error: 'enable_dma' redeclared as different kind of symbol
arch/powerpc/include/asm/dma.h:189: note: previous definition of 'enable_dma' was here
drivers/mtd/nand/r852.c: In function 'r852_engine_enable':
drivers/mtd/nand/r852.c:545: error: implicit declaration of function 'msleep'

Caused by commit 67e054e919248fa1db93de727fb9ad49eb700642 ("mtd: nand:
Add driver for Ricoh xD/SmartMedia reader") from the mtd.

I applied the following patch for today.

From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Mon, 1 Mar 2010 20:21:06 +1100
Subject: [PATCH] mtd: nand: fix name space clash

and include delay.h for msleep().
