Jon Burgess 87c3019d7b V4L/DVB (5592): DMA: Correctly free resources on error, sync PCI streamed data ... I added saa7146_vmalloc_destroy_pgtable() which frees the resources allocated by saa7146_vmalloc_build_pgtable() and updated the callers in budget-core.c and av7110.c. I have also been through the updated functions and updated the error paths to ensure they free all allocated resources on error. I also realised that there are other callers to saa7146_pgtable_free() which did not have any sg DMA mapped so it seems wrong to add the pci_unmap_sg() into that function. Instead I created saa7146_vmalloc_destroy_pgtable() to do this. Also included in this patch are the previous fixes for pci_unmap_sg() and syncing the PCI streamed data to work with a SWIOTLB and match the requirements documented in DMA-API.txt.
