Thanks for noticing, fix below.

Subject: [PATCH] ide: fix for EATA SCSI HBA in ATA emulating mode

IDE probing code used to skip devices attached to EATA SCSI HBA
in ATA emulating mode but because of warm-plug support port I/O
resources are no longer freed if no devices are detected on a port
and the decision about the driver to use is left up to the user.

Remove no longer valid EATA SCSI HBA quirk from do_identify().
