Subject: [dpdk-stable] [dpdk-dev] [PATCH] bus/vmbus: fix wrong allocation for device.name
Date: Thu, 28 May 2020 20:03:07 +0800
Message-ID: <768c74d06680b93b2ce6bbf0813d1910666888dc.1590666521.git.wangyunjian@huawei.com> (raw)

From: Yunjian Wang <wangyunjian@huawei.com>

We do not need and should not allocate memory for device.name.
The device.name should be set point to the devargs->name.

Fixes: 831dba47bd36 ("bus/vmbus: add Hyper-V virtual bus support")
Cc: stable@dpdk.org
