[PATCH 2/2] drivers: scsi: mpt2sas: Clean up error handling for calls to pci_map_single

the out variables. Labels were renamed and gotos altered accordingly. *At the point of the goto free_pci, neither the in nor the out variables are allocated and hence no freeing required. The free_pci label is removed and the goto free_pci is replaced with goto out. Signed-off-by: Tina Johnson

[PATCH 1/2] drivers: scsi: mpt2sas: Added pci_dma_mapping_error() call

Replaced null test on dma handle with pci_dma_mapping_error() o check for mapping errors. Coccinelle was used to find cases that do not check for dma mapping errors: @rule1@ statement S; identifier x; @@ *x = pci_map_single(...); if (!x) S Signed-off-by: Tina Johnson Acked-by: Julia Lawall
