[PATCH 4.4 05/33] net: tehuti: fix error return code in bdx_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
