You need to figure out why this happens yourself. But I can't accept the patch before this is fixed. You could try chmod 644 before committing, but that may not be sufficient. > diff --git a/drivers/usb/serial/option.c b/drivers/usb/serial/option.c > old mode 100644 > new mode 100755 > index ed1e50d..7b52865 > --- a/drivers/usb/serial/option.c > +++ b/drivers/usb/serial/option.c > @@ -252,6 +252,7 @@ static void option_instat_callback(struct urb *urb); > #define QUECTEL_PRODUCT_EG95 0x0195 > #define QUECTEL_PRODUCT_BG96 0x0296 > #define QUECTEL_PRODUCT_EP06 0x0306 > +#define QUECTEL_PRODUCT_EM05G 0x030a > #define QUECTEL_PRODUCT_EM12 0x0512 > #define QUECTEL_PRODUCT_RM500Q 0x0800 > #define QUECTEL_PRODUCT_EC200S_CN 0x6002 > @@ -1134,6 +1135,8 @@ static const struct usb_device_id option_ids[] = { > { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EP06, 0xff, 0xff, 0xff), > .driver_info = RSVD(1) | RSVD(2) | RSVD(3) | RSVD(4) | NUMEP2 }, > { USB_DEVICE_AND_INTERFACE_INFO(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EP06, 0xff, 0, 0) }, > + { USB_DEVICE_INTERFACE_CLASS(QUECTEL_VENDOR_ID, QUECTEL_PRODUCT_EM05G, 0xff), > + .driver_info = RSVD(6) | ZLP }, Checkpatch now also warn of trailing whitespace here.
