* VMW_PVSCSI: Fix the issue of DMA-API related warnings.Josh Boyer2015-12-102-7/+40
| | | | | | | | | | | | | | | The driver is missing calls to pci_dma_mapping_error() after performing the DMA mapping, which caused DMA-API warning to show up in dmesg's output. Though that happens only when DMA_API_DEBUG option is enabled. This change fixes the issue and makes pvscsi_map_buffers() function more robust.
