Subject[PATCH v2 2/2] mmc: atmel: get rid of struct mci_dma_data
Date
As struct mci_dma_data is now only used by AVR32, it is nothing but
pointless indirection. Replace it with struct dw_dma_slave in the
AVR32 platform code and with a void pointer elsewhere.

Signed-off-by: Mans Rullgard <mans@mansr.com>

Changes:
- rebase onto v4.4-rc8: some members of struct dw_dma_slave had been
renamed in an unsubmitted patch
