Subject: [PATCH] xenbus: fix error exit in xenbus_init()
Date: Tue, 22 Aug 2023 11:11:38 +0200	[thread overview]
Message-ID: <20230822091138.4765-1-jgross@suse.com> (raw)

In case an error occurs in xenbus_init(), xen_store_domain_type should
be set to XS_UNKNOWN.

Fix one instance where this action is missing.

Fixes: 5b3353949e89 ("xen: add support for initializing xenstore later as HVM domain")
