- * If the device is in bypass, then that is an error condition in
- * the caller code that is not detected by this fn, whereas jtag_add_dr_scan()
- * does detect it. Similarly if the device is not in bypass, data must
- * be passed to it.
- *
- * If anything fails, then jtag_error will be set and jtag_execute() will
- * return an error. There is no way to determine if there was a failure
- * during this function call.
- *
- * Note that this jtag_add_dr_out can be defined as an inline function.
