[PATCH 4.19 07/72] net: tehuti: fix error return code in bdx_probe()

From: Greg Kroah-Hartman
Date: Mon Mar 29 2021 - 04:14:34 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.
