Subject: [PATCH 2/2] vfio/mdev: don't warn if ->request is not set
Date: Mon, 26 Jul 2021 16:35:24 +0200	[thread overview]
Message-ID: <20210726143524.155779-3-hch@lst.de> (raw)
In-Reply-To: <20210726143524.155779-1-hch@lst.de>

Only a single driver actually sets the ->request method, so don't print
a scary warning if it isn't.
