commit 58aec91efb93338d1cc7acc0a93242613a2a4e5f upstream.
dma-direct.h is introduced in commit d4b6f1562a3c3284 ("LoongArch: Add Non-Uniform Memory Access (NUMA) support"). In commit c78c43fe7d42524c ("LoongArch: Use acpi_arch_dma_setup() and remove ARCH_HAS_PHYS_TO_DMA"), ARCH_HAS_PHYS_TO_DMA was deselected and the coresponding phys_to_dma()/ dma_to_phys() functions were removed. However, the unused dma-direct.h was left behind, which is removed by this patch.
