Ping ...

Which git tree should these patches go into? ATA or SCSI?

Lin Ming (6):
    ata: make ata port as parent device of scsi host
    [SCSI] add flag to skip the runtime PM calls on the host
    [SCSI] check runtime PM status in system PM
    [SCSI] sd: check runtime PM status in sd_shutdown
    ata: add ata port system PM callbacks
    ata: add ata port runtime PM callbacks
