From 87ac1a5296291d557080fb544f445be3bce6c51f Mon Sep 17 00:00:00 2001 From: Kalesh AP Date: Mon, 23 Feb 2015 04:20:15 -0500 Subject: [PATCH] be2net: refactor adapter resource cleanup sequence into be_cleanup() 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. Signed-off-by: Kalesh AP Signed-off-by: Sathya Perla Signed-off-by: David S.
