From 6a11f0f588865f7f8bf2841d9a904c01158ada59 Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Mon, 15 Jul 2019 00:18:44 -0300 Subject: media: ngene: 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.
