[PATCH 6.6 02/93] LoongArch: Remove the unused dma-direct.h

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Miao Wang <shankerwangmiao@xxxxxxxxx>

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.
