Subject: [PATCH] ata: libata-core: Do not try to set sleeping devices to standby
Date: Thu, 11 Jan 2024 20:15:12 +0900 [thread overview]
Message-ID: <20240111111512.1255875-1-dlemoal@kernel.org> (raw)
In ata ata_dev_power_set_standby(), check that the target device is not
sleeping. If it is, there is no need to do anything.
Fixes: aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop")
