5e955245d6 ide: always kill the whole request on error
* Use blk_rq_bytes() instead of obsolete ide_rq_bytes() in ide_kill_rq()
  and ide_floppy_do_request() for failed requests.
  [ bugfix part ]

* Use blk_rq_bytes() instead of obsolete ide_rq_bytes() in ide_do_devset()
  and ide_complete_drive_reset().  Then remove ide_rq_bytes().
  [ cleanup part ]

fdd88f0af6 ide: inline SELECT_DRIVE()
Since SELECT_DRIVE() has boiled down to a mere dev_select() method call, it now
makes sense to just inline it...

130e886708 ide: remove ide_end_request()
* Add ide_rq_bytes() helper.

* Add blk_noretry_request() quirk to ide_complete_rq() (currently only fs
  requests can be marked as "noretry" so there is no change in behavior).

* Switch current ide_end_request() users to use ide_complete_rq().

  [ No need to check for rq->nr_sectors == 0 in {ide_dma,task_pio}_intr(),
    nsectors == 0 in cdrom_end_request() and err == 0 in ide_do_devset(). ]

* Remove no longer needed ide_end_request().

6902a53312 ide: pass error value to ide_complete_rq()
Set rq->errors at ide_complete_rq() call sites and then pass
error value to ide_complete_rq().

[ Some rq->errors assignments look really wrong but this patch
  leaves them alone to not introduce too many changes at once. ]

- drop unused 'cmd' argument from ide_{cmd,task}_ioctl()
- drop unused 'task' argument from tx4939ide_tf_load_fixup()

- use consistent naming for struct ide_cmd variables

a09485df9c ide: move request type specific code from ide_end_drive_cmd() to callers (v3)
* Move request type specific code from ide_end_drive_cmd() to callers.

* Remove stale ide_end_drive_cmd() documentation and drop no longer
  used 'stat' argument.  Then rename the function to ide_complete_rq().

v2:
* Fix handling of blk_pm_request() requests in task_no_data_intr().

v3:
* Some ide_no_data_taskfile() users (HPA code and HDIO_DRIVE_* ioctls
  handlers) access original command later so we need to update it in
  ide_complete_task().

There should be no functional changes caused by this patch.
