Subject: [PATCH 2/2] iommu/amd: Clarify AMD IOMMUv2 initialization messages
Date: Tue, 23 Nov 2021 11:55:07 +0100	[thread overview]
Message-ID: <20211123105507.7654-3-joro@8bytes.org> (raw)
In-Reply-To: <20211123105507.7654-1-joro@8bytes.org>

From: Joerg Roedel <jroedel@suse.de>

The messages printed on the initialization of the AMD IOMMUv2 driver
have caused some confusion in the past. Clarify the messages to lower
the confusion in the future.
