In reply to: Bartlomiej Zolnierkiewicz: "[PATCH 17/18] ide: add ide_read_bcount_and_ireason() helper"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

* Remove no longer needed ->INB, ->OUTB and ->OUTBSYNC methods.

Then:

* Remove no longer used default_hwif_[mm]iops() and ide_[mm_]outbsync().

* Cleanup SuperIO handling in ns87415.c.

There should be no functional changes caused by this patch.
