[PATCH] libata CHS: calculate read/write commands and protocol on the fly (revise #6)
- merge ata_prot_to_cmd() and ata_dev_set_protocol() as ata_rwcmd_protocol() - pave road for read/write multiple support - remove usage of pre-cached command and protocol values and call ata_rwcmd_protocol() instead Signed-off-by: Albert Lee <albertcc@tw.ibm.com> ============== Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
