From 4c44d4634b5c90993fccca9f155347221df6f877 Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Fri, 28 Jun 2019 10:47:19 +0800 Subject: IB: Remove unneeded memset In commit af7ddd8a627c ("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"), dma_alloc_coherent/dmam_alloc_coherent always zeroed the returned memory. So the memset after a coherent allocation function is not needed.
