[PATCH] libata: convert @post_reset to @flags in ata_dev_read_id()
Make ata_dev_read_id() take @flags instead of @post_reset. Currently there is only one flag defined - ATA_READID_POSTRESET, which is equivalent to @post_reset. This is preparation for polling presence detection. Signed-off-by: Jeff Garzik <jeff@garzik.org>
