Do we still need the scsi IPR driver ?

Polling people here: Do we still need the scsi IPR driver for IBM Power
Linux RAID adapters (IBM iSeries: 5702, 5703, 2780, 5709, 570A, 570B
adapters) ?

The reason I am asking is because this driver is the *only* libsas/ata
driver that does not define a ->error_handler port operation. If this
driver is removed, or if it is modified to use a ->error_handler operation
to handle failed commands, then a lot of code simplification can be done
in libata, which I am trying to do to facilitate the processing of some
special error completion for commands using a command duration limit.

Thoughts ?
