[libata] SCSI: simple TEST UNIT READY simulation
It's trivial to ping the device, and that's a much more sane behavior
than no-op.

Thanks for debugging!
Can you tell me something about this device?
[ 49.045635] ata2.00: ATA-6: Config Disk, RGL10364, max UDMA/133
[ 49.051677] ata2.00: 640 sectors, multi 1: LBA
[ 49.056321] ata2.00: configured for UDMA/133
It seems like it does not support the 'check power mode' command.
Can you post a text file attachment, containing the output of 'hdparm
--Istdout' ?
ATA spec says "The device shall return command aborted if the device
does not support the Power Management feature set." Whereas TEST UNIT
READY is required for SCSI. It seems the SAT authors didn't consider
this case.
I assume we can tell from the identify data that the device doesn't
support power management and just fake success for TEST UNIT READY in
this case?
