Most changes in this patch and the subsequent patches, except for the
removal of variables that became superfluous and indentation adjustments,
have been generated as follows:
git grep -lE 'ib_(sg_|)dma_' |
xargs -d\\n \
sed -i -e
's/\([^[:alnum:]_]\)ib_dma_\([^(]*\)(\&\([^,]\+\),/\1dma_\2(\3.dma_device,/g' \
