Subject: [PATCH v9 1/9] hw/vfio/common: Remove error print on mmio region translation by viommu
Date: Mon, 23 Mar 2020 14:16:09 +0530	[thread overview]
Message-ID: <20200323084617.1782-2-bbhushan2@marvell.com> (raw)
In-Reply-To: <20200323084617.1782-1-bbhushan2@marvell.com>

On ARM, the MSI doorbell is translated by the virtual IOMMU.
As such address_space_translate() returns the MSI controller
MMIO region and we get an "iommu map to non memory area"
message. Let's remove this latter.
