Subject: [PATCH 5.8 357/464] liquidio: Fix wrong return value in cn23xx_get_pf_num()
From: Tianjia Zhang <tianjia.zhang@...ux.alibaba.com>
[ Upstream commit aa027850a292ea65524b8fab83eb91a124ad362c ]
On an error exit path, a negative error code should be returned
instead of a positive return value.
Fixes: 0c45d7fe12c7e ("liquidio: fix use of pf in pass-through mode in a virtual machine")
