[libata] EH: freeze port before aborting commands Call the ->freeze() hook before aborting qc's, because some hardware requires special handling prior to accessing the taskfile registers (for diagnosis/analysis/reset). Most notably, hardware may wish to disable the DMA engine or interrupts in the ->freeze() hook. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
