The function __ata_change_queue_depth() uses the helper ata_scsi_find_dev() to get the ata_device structure of a scsi device and set that device maximum queue depth. However, when the ata device is managed by libsas, ata_scsi_find_dev() returns NULL, turning __ata_change_queue_depth() into a nop, which prevents the user from setting the maximum queue depth of ATA devices used with libsas based HBAs. Fix this by renaming __ata_change_queue_depth() to ata_change_queue_depth() and adding a pointer to the ata_device structure of the target device as argument. This pointer is provided by ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of a libata managed device and by sas_change_queue_depth() using sas_to_ata_dev() in the case of a libsas managed ata device.
