Subject: [PATCH 01/12] PCI/switchtec: Use dma_set_mask_and_coherent()

From: Wesley Sheng <wesley.sheng@...rochip.com>

Use dma_set_mask_and_coherent() instead of dma_set_coherent_mask() as
the switchtec hardware fully supports 64bit addressing and we should
set both the streaming and coherent masks the same.
