usb: dwc2: add pci_device_id driver_data parse support

2023-08-22T12:49:12Z

The dwc2 driver has everything we need to run in PCI mode except for pci_device_id driver_data parse. With that to set Loongson dwc2 element and added identified as PCI_VENDOR_ID_LOONGSON and PCI_DEVICE_ID_LOONGSON_DWC2 in dwc2_pci_ids, the Loongson dwc2 controller will work.

usb: dwc2: pci: Move devm_kzalloc() before platform_device_add()

2018-03-13T08:47:44Z

After platform_device_add(), if we error out, we must do platform_device_unregister(), which also does the put. So lets move devm_kzalloc() to simplify error handling and avoid calling of platform_device_unregister().
