| From | Baoquan He <> | Subject | [PATCH 13/22] spi: atmel: Don't use GFP_DMA when calling dma_alloc_coherent() | Date | Sat, 19 Feb 2022 08:52:12 +0800 |
| |
dma_alloc_coherent() allocates dma buffer with device's addressing limitation in mind. It's redundent to specify GFP_DMA when calling dma_alloc_coherent().
