Subject: [PATCH] net: ixp4xx_hss: use dma_pool_zalloc
Date: Sun, 25 Jul 2021 22:42:21 +0800 [thread overview]
Message-ID: <20210725144221.24391-1-wangborong@cdjrlc.com> (raw)
The dma_pool_zalloc combines dma_pool_alloc/memset. Therefore, the
dma_pool_alloc/memset can be replaced with dma_pool_zalloc which is
more compact.
