From af996031e1545c47423dfdd024840702ceb5a26c Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Sun, 25 Jul 2021 22:42:21 +0800 Subject: [PATCH] net: ixp4xx_hss: use dma_pool_zalloc 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. Signed-off-by: Jason Wang Signed-off-by: David S.
