Hello guys,
Currently i've done this in xhci-pci.c
#define PCI_VENDOR_ID_RENESAS 0x1912
#define PCI_DEVICE_ID_RENESAS_UPD720201 0x0014
if (pdev->vendor == PCI_VENDOR_ID_RENESAS &&
pdev->device == PCI_DEVICE_ID_RENESAS_UPD720201 &&
pdev->revision == 0x3)
xhci->quirks |= XHCI_NEC_HOST;
The warnings are gone.
Perhaps this quirk needs to apply to all Renesas controllers ? This addition
i've made obviously specifically matches the card I've got but the NEC match
in xhci-pci.c obviously isn't matching the Renesas vendor ID only NEC.
if (pdev->vendor == PCI_VENDOR_ID_NEC)
xhci->quirks |= XHCI_NEC_HOST;
Maybe this needs an && PCI_VENDOR_ID_RENESAS
Regards,
Will Trives
