From f1545154a5c96590b1992aac8ee1e2c445e301ed Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 16 Jul 2007 14:29:40 +0900 Subject: libata: quickly trigger SATA SPD down after debouncing failed Debouncing failure is a good indicator of basic link problem. Use -EPIPE to indicate debouncing failure and make ata_eh_reset() invoke sata_down_spd_limit() if the error occurs during reset.
