From 45371aa398c6473a722e4a3800d9fea5a53e080f Mon Sep 17 00:00:00 2001 From: Jitendra Bhivare Date: Tue, 10 Oct 2017 16:18:13 +0530 Subject: [PATCH] scsi: be2iscsi: Free msi_name and disable HW intr In beiscsi_dev_probe, allocated msi_name does not get freed and enabled HW interrupts are not disabled in iscsi_host_add error case. Add beiscsi_free_irqs fn to handle the cleanup in probe and disable port. Signed-off-by: Jitendra Bhivare Signed-off-by: Martin K.
