Subject: [PATCH v2 05/10] vfio/ccw: Pass enum to FSM event jumptable
Date: Wed, 15 Jun 2022 22:33:13 +0200	[thread overview]
Message-ID: <20220615203318.3830778-6-farman@linux.ibm.com> (raw)
In-Reply-To: <20220615203318.3830778-1-farman@linux.ibm.com>

The FSM has an enumerated list of events defined.
Use that as the argument passed to the jump table,
instead of a regular int.
