From 1e0d4e6225996f05271de1ebcb1a7c9381af0b27 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Wed, 2 Jun 2021 21:30:29 +0800 Subject: scsi: core: Only put parent device if host state differs from SHOST_CREATED 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.
