Hello, Three libata fixes. * Fix for a circular reference bug in sysfs code which prevented pata_legacy devices from being released after probe failure, which in turn prevented devres from releasing the associated resources. * Drop spurious WARN in the command issue path which can be triggered by a legitimate passthrough command. * A ahci_qoriq specific fix. Thanks.
