Subject: [PATCH v3 2/3] vfio/ccw: Remove FSM Close from remove handlers
Date: Thu, 28 Jul 2022 22:49:13 +0200	[thread overview]
Message-ID: <20220728204914.2420989-3-farman@linux.ibm.com> (raw)
In-Reply-To: <20220728204914.2420989-1-farman@linux.ibm.com>

Now that neither vfio_ccw_sch_probe() nor vfio_ccw_mdev_probe()
affect the FSM state, it doesn't make sense for their _remove()
counterparts try to revert things in this way. Since the FSM open
and close are handled alongside MDEV open/close, these are
unnecessary.
