From 6a24c8fb0d889b39079215970210f88255b81c80 Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Mon, 15 Jul 2019 11:19:21 +0800 Subject: [PATCH] hippi: Remove call to memset after pci_alloc_consistent pci_alloc_consistent calls dma_alloc_coherent directly. In commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So memset is not needed.
