Subject: qla2xxx: Fix schedule_delayed_work() for target timeout calculations
From: Shivaram Upadhyayula <[email protected]>
commit 63832aabec12a28a41a221773ab3819d30ba0a67 upstream.
This patch fixes two cases in qla_target.c code where the
schedule_delayed_work() value was being incorrectly calculated
from sess->expires - jiffies.
