Commit 30dcf76acc69 "libata: migrate ACPI code over to new bindings"
removed ACPI dock notification related code, but there's some dead
code left, so clean up it.
I never noticed this, but it looks to be the case...
I'm not sure the dock notification code is removed intentionally or
mistakenly though, if it is a mistake, then instead of removing the left
code here, we probably should add the dock notification code back.
But I have no test system or any knowledge about how ata dock works, so
I may be wrong :-)
Looks like a regression to me. We're probably locking up on some
older laptops which connects optical drives with hotpluggable PATA.
Matthew, can you please fix it?
Thanks.
Yeah, Aaron is right. We should restore the dock notification
handler to support ATA hotplug on some IBM laptops.
Regards!
