If our length is greater than the size of the buffer, we overflow the buffer
Hmm...
How about this: buf = list->hid_debug_buf; if (list->tail < list->head) { ret = simple_read_from_buffer(buffer, count, &list->head, buf, HID_DEBUG_BUFSIZE); if (ret < 0) break; if (list->head != buf + HID_DEBUG_BUFSIZE) break; list->head = 0; } n = simple_read_from_buffer(buffer + ret, count - ret, &list->head, buf, list->tail); if (n >= 0) ret += n; if (list->head == buf + HID_DEBUG_BUFSIZE) list->head = 0; instead?
