From mboxrd@z Thu Jan 1 00:00:00 1970 From: Fuqian Huang Subject: [PATCH v3 22/24] tty: serial: Remove call to memset after pci_alloc_consistent Date: Mon, 15 Jul 2019 11:20:01 +0800 Message-ID: <20190715032001.7212-1-huangfq.daxian@gmail.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org Cc: Greg Kroah-Hartman , Jiri Slaby , linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org, Fuqian Huang List-Id: linux-serial@vger.kernel.org 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.
