From e675697eaca208edcebb42fd8c30a71bd5258c40 Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Fri, 28 Jun 2019 01:34:34 +0800 Subject: [PATCH] ata: sata_sil24: Remove call to memset after dmam_alloc_coherent In commit af7ddd8a627c ("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),, dmam_alloc_coherent has already zeroed the memory. So memset is not needed.
