Subject: [PATCH 4/8] tools/libvchan: init_xs_srv: Simplify error handling (2)
Date: Fri, 2 Nov 2018 17:01:09 +0000	[thread overview]
Message-ID: <20181102170113.11646-5-ian.jackson@eu.citrix.com> (raw)
In-Reply-To: <20181102170113.11646-1-ian.jackson@eu.citrix.com>

* Abolish fail_xs_open which is now exactly the same as fail.

* Change all gotos to refer to fail instead.

No functional change.
