Subject: [PATCH for-6.0 3/7] hw/block/nvme: fix the nsid 'invalid' value
Date: Wed, 24 Mar 2021 21:09:03 +0100	[thread overview]
Message-ID: <20210324200907.408996-4-its@irrelevant.dk> (raw)
In-Reply-To: <20210324200907.408996-1-its@irrelevant.dk>

From: Klaus Jensen <k.jensen@samsung.com>

The `nvme_nsid()` function returns '-1' (FFFFFFFFh) when the given
namespace is NULL. Since FFFFFFFFh is actually a valid namespace
identifier (the "broadcast" value), change this to be '0' since that
actually *is* the invalid value.
