[PATCH] libata: sync result_tf.flags w/ command tf.flags
libata didn't initialize result_tf.flags which indicates transfer type (RW/FUA) and address type (CHS/LBA/LBA48). ata_gen_fixed_sense() assumed result_tf.flags equals command tf.flags and failed to report the first failed block to SCSI layer because zero tf flags indicates CHS and bad block reporting for CHS is not implemented. Implement fill_result_tf() which sets result_tf.flags to command tf.flags and use it to fill result_tf. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
