net/qla3xxx: switch from 'pci_' to 'dma_' API
[ Upstream commit 41fb4c1ba7478fe34c7e094e124e4ee4513b9763 ]
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'ql_alloc_net_req_rsp_queues()' GFP_KERNEL can
be used because it is only called from 'ql_alloc_mem_resources()' which
already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see below)
When memory is allocated in 'ql_alloc_buffer_queues()' GFP_KERNEL can be
used because this flag is already used just a few line above.
When memory is allocated in 'ql_alloc_small_buffers()' GFP_KERNEL can
be used because it is only called from 'ql_alloc_mem_resources()' which
already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see above)
When memory is allocated in 'ql_alloc_mem_resources()' GFP_KERNEL can be
used because this function already calls 'ql_alloc_buffer_queues()' which
uses GFP_KERNEL. (see above)
While at it, use 'dma_set_mask_and_coherent()' instead of 'dma_set_mask()/
dma_set_coherent_mask()' in order to slightly simplify code.
