3.14.61-rt63-rc1 stable review patch.
If anyone has any objections, please let me know.
------------------
From: "bmouring@xxxxxx" <bmouring@xxxxxx>
In 8930ed80 (rtmutex: Cleanup deadlock detector debug logic),
chainwalking control enums were introduced to limit the deadlock
detection logic. One of the calls to task_blocks_on_rt_mutex was
missed when converting to use the enums.
