All errors (new ones prefixed by >>, old ones prefixed by <<):

ERROR: modpost: "dwc2_pci_ids" [drivers/usb/dwc2/dwc2_pci.ko] undefined!

I test it was set dwc2 pci driver as built-in, so no error, this compile
error was that dwc2_pci_ids not export when driver as module and I will
add EXPORT_SYMBOL_GPL(dwc2_pci_ids) to fix that compile issue.

Thanks.
