[PATCH 2.6.16-rc1] ide-scsi: fix for IDE probe/remove ops changes

[Mikael Pettersson]

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but
fails to find any devices to bind to. It also triggers a message
"Driver 'ide-scsi' needs updating - please use bus_type methods"
from the driver core.

The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the
ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/
was updated for this change but ide-scsi.c wasn't. Hence the breakage.

This patch repairs ide-scsi and also eliminates the driver core warning.
Please apply before 2.6.16 final.
