From 03718db97bfb57535f3aa8110f0cbe0c616a67c0 Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Fri, 6 Jul 2018 11:28:02 +0100 Subject: net: hns3: Fix get_vector ops in hclgevf_main module 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.
