[PATCH 12/22] staging: emxx_udc: Don't use GFP_DMA when calling dma_alloc_coherent()

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

 



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().
