ide: task_end_request() fix
task_end_request() modified to always call ide_end_drive_cmd() for taskfile requests. Previously, ide_end_drive_cmd() was called only when IDE_TFLAG_FLAGGED was set. Also, ide_dma_intr() is modified to use task_end_request(). Enables TASKFILE ioctls to get valid register outputs on successful completion. Bart: - ported it over recent IDE changes Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
