Hi David,

Today's linux-next merge of the mtd tree got a conflict in
drivers/mtd/mtdcore.c between commit
a33eb6b91034c95b9b08576f68be170f995b2c7d ("Move mtd_bdi_*mappable to
mtdcore.c") from Linus' tree and commit
b520e412faaaad35641aeedd6059179f9f1b393c ("mtd: Replace static array of
devices with an idr structure") from the mtd tree.

Just overlapping additions. I fixed it up (see below) and can carry the
fix for a while.
