[PATCH v2] ATA: ahci: Add Intel PCH-S RAID device ID

From: Roman Gardzinski

Date: Thu Oct 29 2026 - 10:11:29 EST


When the Intel Nova Lake SATA controller is configured in RAID mode (rather
than AHCI), the generic entry in ahci_pci_tbl which matches any device with
the PCI class code for AHCI, is not sufficient, since the SATA controller
in RAID mode uses a different PCI class code.
