+static inline struct io_tlb_mem *get_io_tlb_mem(struct device *dev) +{ +#ifdef CONFIG_DMA_RESTRICTED_POOL + if (dev && dev->dma_io_tlb_mem) + return dev->dma_io_tlb_mem; +#endif /* CONFIG_DMA_RESTRICTED_POOL */ + + return io_tlb_default_mem;
Given that we're also looking into a not addressing restricted pool I'd rather always assign the active pool to dev->dma_io_tlb_mem and do away with this helper.
