ata: libata-core: Do not try to set sleeping devices to standby
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") Cc: stable@vger.kernel.org Signed-off-by: Damien Le Moal <dlemoal@kernel.org> Signed-off-by: Niklas Cassel <cassel@kernel.org>
