Subject: linux-next: manual merge of the arm-soc tree with the l2-mtd tree

Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
drivers/mtd/nand/Kconfig between commit 212012138deb ("mtd: nand: omap2:
updated support for BCH4 ECC scheme") from the l2-mtd tree and commit
930d800bded7 ("mtd: omap2: allow bulding as a module") from the arm-soc
tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
