[PATCH] usb: xhci-pci: Add AMD 600 series to xhci-pci-prom21

From: Stephen Horvath

Date: Tue Aug 18 2026 - 01:36:05 EST


It seems the xhci-pci-prom21 module only has IDs for the 800 series
chipsets. However, this also seems to work for my X670 board, so I have
added its DID (`0x43f7`) to the list.

`1022:43f7` also seems to be the only DID for the 600 series, on the PCI
ID database (https://pci-ids.ucw.cz/read/PC/1022/43f7).
