Recent MTD changes caused a minor build regression on OMAP1:
In file included from arch/arm/mach-omap1/devices.c:31:
arch/arm/mach-omap1/common.h:85:39: error: 'struct nand_chip' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
Fixes: 1002aed789bc ("mtd: rawnand: plat_nand: Pass a nand_chip object to all platform_nand_ctrl hooks")

Hi Arnd,
Thanks for the fix, sorry for breaking the build.

Currently I see "#include <linux/mtd/mtd.h>" at the top of this file.
That's where the "struct mtd_info" that has been replaced by a "struct
nand_chip" was declared. The nand_chip object is declared in
<linux/mtd/rawnand.h>.
I think you can remove this include (unneeded anymore for what I see).
Then, either you keep the nand_chip forward declaration, or replace the
mtd.h include into the rawnand.h one?
Thanks,
Miquèl
