Subject: linux-next: manual merge of the mmc tree with the slave-dma tree

Hi Chris,

Today's linux-next merge of the mmc tree got a conflict in
drivers/mmc/host/sh_mmcif.c between commits 916001fe33b7 ("mmc: sh_mmcif:
remove unneeded struct sh_mmcif_dma, prepare to shdma conversion") and
0e79f9ae1610 ("mmc: sh_mmcif: switch to the new DMA channel allocation
and configuration") from the slave-dma tree and commit bf68a812f06c
("mmc: sh-mmcif: add OF support, make platform data optional") from the
mmc tree.

I fixed it up (see below) and can carry the fix as necessary.
