Subject: [PATCH 4/4] scsi: core: only put parent device if host state isn't in SHOST_CREATED
Date: Wed,  2 Jun 2021 21:30:29 +0800	[thread overview]
Message-ID: <20210602133029.2864069-5-ming.lei@redhat.com> (raw)
In-Reply-To: <20210602133029.2864069-1-ming.lei@redhat.com>

get_device(shost->shost_gendev.parent) is called after host state is
changed to SHOST_RUNNING. So scsi_host_dev_release() shouldn't release
the parent device if host state is still SHOST_CREATED.
