Hi all,

Today's linux-next merge of the mtd tree got a conflict in:

  drivers/mtd/mtdpart.c

between commit:

  2b6f0090a333 ("mtd: Check add_mtd_device() ret code")

from Linus' tree and commit:

  2c24c9af0f38 ("mtd: rework partitions handling")

from the mtd tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Stephen Rothwell
