[PATCH 2/2] ata: libata-core: Apply ATI NCQ horkage to ASPEED as well

From: Patrick McLean
Date: Mon Apr 17 2023 - 21:17:35 EST


We have some machines with ASPEED SATA controllers, and are seeing the same NCQ
issues that ATI controllers (I am not sure if it's a rebranded ATI controller,
or they both have some faulty implementation). This NCQ breakage is consistent
across a few different types of drives.

Instead of maintaining a list of drives that are broken with ASPEED controllers
as well as ATI, let's just treat ASPEED controllers like ATI ones, and disable
NCQ on drives that have ATA_HORKAGE_NO_NCQ_ON_ATI set on them.

We have been running this patch on several machines for over a week now without
reproducing an issue that was happening almost daily before.
