From: Jason Wang Date: Sun, 25 Jul 2021 14:42:21 +0000 (+0800) Subject: net: ixp4xx_hss: use dma_pool_zalloc X-Git-Tag: v5.15-rc1~157^2~393 X-Git-Url: https://repo.jachan.dev/linux.git/commitdiff_plain/af996031e1545c47423dfdd024840702ceb5a26c?hp=-c 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.
