The "dev->buffer_overflow = 1" line is indented to the same level as the
preceding "dev_warn" line, which makes it appear as though it is supposed
to belong to the same "else" case as the dev_warn. The actual code looks
like this:
if (urb->actual_length > 0) {
next_ring_head = (dev->ring_head+1) % ring_buffer_size;
if (next_ring_head != dev->ring_tail) {
...
} else
dev_warn(&dev->intf->dev,
"Ring buffer overflow, %d bytes dropped\n",
urb->actual_length);
+ dev->buffer_overflow = 1;
}
You see the problem?
