Subject: [PATCH 21/47] nvme: move the call to nvme_init_identify earlier
Date: Sat, 21 Nov 2015 08:20:01 +0100
Message-ID: <1448090427-18749-22-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1448090427-18749-1-git-send-email-hch@lst.de>

We want to record the identify and CAP values even if no I/O queue
is available.
