Subject: [PATCH] iommu/arm-smmu-v3: suppress MSI allocation failure message
Date: Wed, 17 Jan 2018 13:39:59 -0500 [thread overview]
Message-ID: <1516214399-24012-1-git-send-email-nwatters@codeaurora.org> (raw)
From: Sinan Kaya <okaya@codeaurora.org>
Even though QDF2400 supports MSI interrupts with SMMUv3, it is not enabled
in ACPI FW to preserve compatibility with older kernel versions. Code is
emitting warning message during boot.
This is causing some test tools to record a false warning and is causing
support issues.
Better reduce the message level.
