- * Name: nxcon_semwait and nxcon_sempost
- *
- * Description:
- *   If debug is on, then lower level code may attempt console output while
- *   we are doing console output!  In this case, we will toss the nested
- *   output to avoid deadlocks and infinite loops.
- *
- * Input Parameters:
- *   priv - Driver data structure
- *
- * Returned Value:
- *
