I can rename it, no problem. It looks to me a little bit redundant
information as these are just wrappers over dma_{map,unmap}_sg_attrs()
where the attrs are also used. Everything there refers to the mapping of
scatter gather list. Anyway, renaming won't harm neither so let me send
a follow up only for this patch.
Thanks for feedback!
Krzysztof

Update only to this patch from the set.
Changes since v6:
1. Rename attrs->dma_attrs arguments in map/unmap functions (suggested
by Bart Van Assche).

This is an update only to this patch from the set.
Changes since v6.1:
1. Rename attrs->dma_attrs everywhere.
Changes since v6:
1. Rename attrs->dma_attrs arguments in map/unmap functions (suggested
by Bart Van Assche).
