Subject:    [PATCH v2 3/4] IB/ehca: remove ib_sg_dma_address() and ib_sg_dma_len() overloads
From:       Mike Marciniszyn <mike.marciniszyn () intel ! com>

[Download RAW message or body]

These methods appear to only mimic the sg_dma_address()
and sg_dma_len() behavior.

They can be safely removed.
