Subject: [PATCH 09/11] scsi: hisi_sas: remove redundant handling to event95 for v3
Date: Wed, 2 May 2018 23:56:32 +0800 [thread overview]
Message-ID: <1525276594-92173-10-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1525276594-92173-1-git-send-email-john.garry@huawei.com>
From: Xiaofei Tan <tanxiaofei@huawei.com>
Event95 is used for DFX purpose. The relevant bit for this
interrupt in the ENT_INT_SRC_MSK3 register has been disabled,
so remove the processing.
