Subject: [Qemu-devel] [PATCH 2/5] hw/scsi/spapr_vscsi: Remove superfluous memset
Date: Thu, 8 Oct 2015 21:35:13 +0200 [thread overview]
Message-ID: <1444332916-16476-3-git-send-email-thuth@redhat.com> (raw)
In-Reply-To: <1444332916-16476-1-git-send-email-thuth@redhat.com>
g_malloc0 already clears the memory, so no need for
the additional memset here.
