| Subject: qmi_wwan: fix interface number for DW5821e production firmware |
| |
| From: Aleksander Morgado <aleksander@aleksander.es> |
| |
| [ Upstream commit f25e1392fdb556290957142ac2da33a02cbff403 ] |
| |
| The original mapping for the DW5821e was done using a development |
| version of the firmware. Confirmed with the vendor that the final |
| USB layout ends up exposing the QMI control/data ports in USB |
| config #1, interface #0, not in interface #1 (which is now a HID |
| interface). |
