| From | Greg Kroah-Hartman <> | Subject | [PATCH 4.19 65/67] scsi: core: Only put parent device if host state differs from SHOST_CREATED | Date | Mon, 14 Jun 2021 12:27:48 +0200 |
| |
From: Ming Lei <ming.lei@redhat.com>
commit 1e0d4e6225996f05271de1ebcb1a7c9381af0b27 upstream.
get_device(shost->shost_gendev.parent) is called after host state has switched to SHOST_RUNNING. scsi_host_dev_release() shouldn't release the parent device if host state is still SHOST_CREATED.
