From: Bartlomiej Zolnierkiewicz Subject: [PATCH] ide: fix registers loading order for WIN_SMART in execute_drive_cmd() Fix registers loading order for REQ_TYPE_ATA_CMD request with WIN_SMART command in execute_drive_cmd() (load IDE_FEATURE_REG and IDE_SECTOR_REG before loading IDE_LCYL_REG and IDE_HCYL_REG). It shouldn't affect anything (just a usual paranoia to separate changes which change the way in which hardware is accessed from code cleanups).
