From: Zhang Qiang <qiang.zh...@windriver.com>
The data structure member "wq->rescuer" was reset to a null pointer
in one if branch. It was passed to a call of the function "kfree"
in the callback function "rcu_free_wq" (which was eventually executed).
The function "kfree" does not perform more meaningful data processing
for a passed null pointer (besides immediately returning from such a call).
Thus delete this function call which became unnecessary with the referenced
software update.
Fixes: def98c84b6cd ("workqueue: Fix spurious sanity check failures in
destroy_workqueue()")
