Hi all,
According to Documentation/DMA-mapping.txt one should
check the return value of pci_map_single()/pci_map_page()
using pci_dma_mapping_error(), but many drivers do not.
(I have checked in drivers/net/* for example).
Should we add __must_check in the definitions/declarations
of these functions/macros "to force" the check?
Best regards
