From: Sathya Perla <sathya.perla@...lex.com>
To: <netdev@...r.kernel.org>
Subject: [net-next PATCH 4/9] be2net: use a wrapper to schedule and cancel error detection task
Also rename func_recovery_work/task to err_detection_work/task as error
detection is the primary goal of this task while recovery is not guaranteed.
