Subject: [PATCH] net: ixp4xx_hss: use dma_pool_zalloc
Date:   Sun, 25 Jul 2021 22:42:21 +0800
Message-Id: <20210725144221.24391-1-wangborong@cdjrlc.com>

Precedence: bulk

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.
