ata_host_release() uses drvdata to determine ata_host to release and

This bug was first analyzed by Alan Cox for pata_pcmcia.

Alan, this is the bug you talked about, right? I took the fix from
"[BUG] PATA_PCMCIA does not work" and expanded it. If this isn't the
one, please let me know. Thanks.
Has a tester confirmed that this patch fixes the problem, and supercedes
Alan's patch?
