Subject: [PATCH net-next 06/12] net: hns3: fix incomplete uninitialization of IRQ in the hns3_nic_uninit_vector_data()
Date: Tue, 18 Dec 2018 19:37:53 +0800	[thread overview]
Message-ID: <1545133079-79605-7-git-send-email-lipeng321@huawei.com> (raw)
In-Reply-To: <1545133079-79605-1-git-send-email-lipeng321@huawei.com>

From: Huazhong Tan <tanhuazhong@huawei.com>

In the hns3_nic_uninit_vector_data(), the procedure of uninitializing
the tqp_vector's IRQ has not set affinity_notify to NULL and changes
its init flag. This patch fixes it. And for simplificaton, local
variable tqp_vector is used instead of priv->tqp_vector[i].

Fixes: 424eb834a9be ("net: hns3: Unified HNS3 {VF|PF} Ethernet Driver for hip08 SoC")
