Hello Hans Verkuil,
The patch 59aea928d57f: "[media] go7007: don't continue if firmware
can't be loaded" from Mar 17, 2013, leads to the following static
checker warning:
drivers/media/usb/go7007/go7007-usb.c:1292 go7007_usb_probe()
warn: we tested 'board->flags & (1 << 0)' before and it was 'true'
drivers/media/usb/go7007/go7007-usb.c
1289
1290 /* Allocate the URBs and buffers for receiving the audio stream
*/
1291 if ((board->flags & GO7007_USB_EZUSB) &&
1292 (board->flags & GO7007_BOARD_HAS_AUDIO)) {
We used to test "go->audio_enabled" enabled here. The GO7007_USB_EZUSB
and GO7007_BOARD_HAS_AUDIO are different names for BIT(0).
1293 for (i = 0; i < 8; ++i) {
1294 usb->audio_urbs[i] = usb_alloc_urb(0,
GFP_KERNEL);
1295 if (usb->audio_urbs[i] == NULL)
1296 goto allocfail;
1297 usb->audio_urbs[i]->transfer_buffer =
kmalloc(4096,
1298
GFP_KERNEL);
1299 if (usb->audio_urbs[i]->transfer_buffer == NULL)
1300 goto allocfail;
1301 usb_fill_bulk_urb(usb->audio_urbs[i],
usb->usbdev,
1302 usb_rcvbulkpipe(usb->usbdev, 8),
1303 usb->audio_urbs[i]->transfer_buffer,
4096,
1304 go7007_usb_read_audio_pipe_complete,
go);
1305 }
1306 }
