This code was apparently copied to the USB gadget detection code (g_dnl_board_usb_cable_connected()), but here we actually *expect* external VBUS power, so a warning is wrong and confusing. So far this message rarely triggered, but a recent patch (6fa41cdd19b9) changed this: =========================== => ums 0 mmc 2 UMS: LUN 0, dev mmc 2, hwpart 0, sector 0x0, count 0xe90000 A charger is plugged into the OTG /A charger is plugged into the OTG \A charger is plugged into the OTG |A charger is plugged into the OTG -A charger is plugged into the OTG .... =========================== Remove the message for the gadget cable detection call, and just return the status of the VBUS detection, as this is what the callers are after.
