1. In swiotlb_alloc_coherent, the branch of __get_free_pages. Directly
return vaddr on success, and pass vaddr to free_pages on failure.
2. So, we can directly transparent pass vaddr from __dma_free to
swiotlb_free_coherent, keep consistent with swiotlb_alloc_coherent.
This patch have no
1. In swiotlb_alloc_coherent, the branch of __get_free_pages. Directly
return vaddr on success, and pass vaddr to free_pages on failure.
2. So, we can directly transparent pass vaddr from __dma_free to
swiotlb_free_coherent, keep consistent with swiotlb_alloc_coherent.
