[PATCH] ide-scsi 2.5.10-dj1 compilation failure

[Douglas Gilbert <dougg@torque.net>]

Christoph Lameter <christoph@lameter.com> reported this
compile error in lk 2.5.10-dj1:
> ide-scsi.c:837: unknown field `abort' specified in initializer
> ide-scsi.c:837: warning: initialization from incompatible pointer type
> ide-scsi.c:838: unknown field `reset' specified in initializer
> ide-scsi.c:838: warning: initialization from incompatible pointer type

Below is a patch which attempts to do the right thing:
it wires up the scsi new eh handling and attempts to do
a device reset.

It has been tested and oopses in start_request() inside
ide.c when a device reset is issued :-) Since the previous
ide-scsi logic just ignored scsi error handling, it isn't
really a whole lot worse. There is a "fix me" at the
appropriate point.
