From 0998a63b493b8591bea9e81144f8ed05e0a92cef Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Mon, 15 Jul 2019 11:20:01 +0800 Subject: tty: serial: 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.
