Subject: [PATCH V2 2/2] scsi: core: put shost->shost_gendev in failure handling path
Date: Fri, 28 May 2021 09:18:38 +0800	[thread overview]
Message-ID: <20210528011838.2122559-3-ming.lei@redhat.com> (raw)
In-Reply-To: <20210528011838.2122559-1-ming.lei@redhat.com>

get_device(&shost->shost_gendev) is called in scsi_add_host_with_dma(),
but its counter pair isn't called in the failure path, so fix it
by calling put_device(&shost->shost_gendev) in its failure path.
