[PATCH 4.14 07/59] net: tehuti: fix error return code in bdx_probe()
From: Greg Kroah-Hartman
Date: Mon Mar 29 2021 - 04:10:08 EST
From: Jia-Ju Bai <baijiaju1990@xxxxxxxxx>
[ Upstream commit 38c26ff3048af50eee3fcd591921357ee5bfd9ee ]
When bdx_read_mac() fails, no error return code of bdx_probe()
is assigned.
To fix this bug, err is assigned with -EFAULT as error return code.
