From fd3a6837d8e18cb7be80dcca1283276290336a7a Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Mon, 6 Nov 2023 13:00:49 +0900 Subject: ata: libata-core: Fix ata_pci_shutdown_one() This reverts commit 5b6fba546da246b3d0dd8465c07783e22629cc53. Commit 5b6fba546da2 ("ata: libata-core: Detach a port devices on shutdown") modified the function ata_pci_shutdown_one() to stop (suspend) devices attached to the ports of a PCI AHCI adapter to ensure that drives are spun down before shutting down a system. However, this is done only for PCI adapters and not for other types of adapters. This limitation was addressed with commit 24eca2dce0f8 ("scsi: sd: Introduce manage_shutdown device flag"). With this, all ATA disks are spun down on system shutdown, which make the changes introduced with 5b6fba546da2 useless.
