[PATCH 02/22] net: moxa: Don't use GFP_DMA when calling dma_alloc_coherent()

From: Baoquan He
Date: Fri Feb 18 2022 - 19:53:13 EST


From: Hyeonggon Yoo <42.hyeyoo@xxxxxxxxx>

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().
