Message-ID: <1424683216-29611-9-git-send-email-sathya.perla@emulex.com>

Subject: [net-next PATCH 8/9] be2net: refactor adapter resource cleanup sequence into be_cleanup()
From: Kalesh AP <kalesh.purayil@...lex.com>
Most of the resource cleanup sequences performed in be_suspend(),
be_eeh_err_detected() and be_err_detection_task() are same. Moved the
common code to a new routine be_cleanup() to avoid code duplication.
