DESCRIPTION

26       Read ID data from the specified device. ATA_CMD_ID_ATA is performed on
27       ATA devices and ATA_CMD_ID_ATAPI on ATAPI devices. This function also
28       issues ATA_CMD_INIT_DEV_PARAMS for pre-ATA4 drives.

FIXME

31       ATA_CMD_ID_ATA is optional for early drives and right now we abort if
32       we hit that case.
33

LOCKING

35       Kernel thread context (may sleep)
36

RETURNS

38       0 on success, -errno otherwise.
