Subject: [PATCH 8/8] hw/cxl/mailbox: Use new UUID network order define for cel_uuid
Date: Wed, 11 Jan 2023 14:24:40 +0000	[thread overview]
Message-ID: <20230111142440.24771-9-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20230111142440.24771-1-Jonathan.Cameron@huawei.com>

From: Ira Weiny <ira.weiny@intel.com>

The cel_uuid was programatically generated previously because there was
no static initializer for network order UUIDs.

Use the new network order initializer for cel_uuid.  Adjust
cxl_initialize_mailbox() because it can't fail now.

Update specification reference.
