From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
Subject: [PATCH] ide: use ide_complete_cmd() for REQ_UNPARK_HEADS

* Fixup ->tf_flags in ide_do_park_unpark() to match their current use.

* Use ide_complete_cmd() for REQ_UNPARK_HEADS.

While at it:

* No need to read Error register for PM requests in task_no_data_intr().
