vp702x: comment dead code

Hello Mauro Carvalho Chehab,

The patch 269d91f53fe3: "[media] vp702x: comment dead code" from Apr 29, 2015, leads to the following static checker warning:

drivers/media/usb/dvb-usb/dvb-usb-remote.c:128 legacy_dvb_usb_read_remote_control()
error: uninitialized symbol 'state'.

drivers/media/usb/dvb-usb/dvb-usb-remote.c
108 static void legacy_dvb_usb_read_remote_control(struct work_struct *work) 109 {
110 struct dvb_usb_device *d =
111 container_of(work, struct dvb_usb_device, rc_query_work.work);
112 u32 event;
113 int state;
114
115 /* TODO: need a lock here. We can simply skip checking for the remote control
116 if we're busy. */
117
118 /* when the parameter has been set to 1 via sysfs while the driver was running */
119 if (dvb_usb_disable_rc_polling)
120 return;
121

   122          if (d->props.rc.legacy.rc_query(d,&event,&state)) {
                                       ^^^^^^^^^^^^^^^^^^^^^^^^^

This sometimes returns zero without doing anything like in vp702x_rc_query().

   123                  err("error while querying for an remote control event.");
   124                  goto schedule;
   125          }
   126  
   127  
   128          switch (state) {
   129                  case REMOTE_NO_KEY_PRESSED:
   130                          break;
   131                  case REMOTE_KEY_PRESSED:
   132                          deb_rc("key pressed\n");
   133                          d->last_event = event;
   134                  case REMOTE_KEY_REPEAT:
   135                          deb_rc("key repeated\n");
   136                          input_event(d->input_dev, EV_KEY, event, 1);
   137                          input_sync(d->input_dev);
   138                          input_event(d->input_dev, EV_KEY, d->last_event, 0);
   139                          input_sync(d->input_dev);
   140                          break;
   141                  default:
   142                          break;
   143          }
