Subject: [PATCH net-next 08/10] net: hns3: Fix get_vector ops in hclgevf_main module
Date: Fri, 6 Jul 2018 11:28:02 +0100	[thread overview]
Message-ID: <20180706102804.196-9-salil.mehta@huawei.com> (raw)
In-Reply-To: <20180706102804.196-1-salil.mehta@huawei.com>

From: Yunsheng Lin <linyunsheng@huawei.com>

The hclgevf_free_vector function expects the caller to pass
the vector_id to it, and hclgevf_put_vector pass vector to
it now, which will cause vector allocation problem.

This patch fixes it by converting vector into vector_id before
calling hclgevf_free_vector.

Fixes: e2cb1dec9779 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support")
