dma-mapping: remove an outdated comment from dma-map-ops.h

suijingfeng · Christoph Hellwig · commit 5935b8377a0f · 2024-10-29T08:53:37.000+01:00
The "/* CONFIG_ARCH_HAS_DMA_COHERENCE_H */" was an description about the ARCH_HAS_DMA_COHERENCE_H configure option, but it has been removed since the dma_default_coherent variable was lifted from the mips architecture to the driver core. Therefore it doesn't match any compile guard now. Just remove it. Fixes: 6d4e9a8 ("driver core: lift dma_default_coherent into common code") Signed-off-by: Sui Jingfeng <sui.jingfeng@linux.dev> Signed-off-by: Christoph Hellwig <hch@lst.de>
