Subject: [PATCH 7/20] ide: set IDE_TFLAG_IN_* flags before queuing/executing command
Date: Sun, 9 Dec 2007 22:12:02 +0100 [thread overview]
Message-ID: <200712092212.02712.bzolnier@gmail.com> (raw)
* Add IDE_TFLAG_{HOB,TF,DEVICE} defines.
* Set IDE_TFLAG_IN_* flags in {do_rw,ide_no_data,ide_raw}_taskfile() users.
* Remove no longer needed ->tf_flags setup from ide_end_drive_cmd().
There should be no functionality changes caused by this patch.
