Subject: [PATCH] net: mellanox: mlx5: fix error return code in mlx5_fpga_device_start()
Date: Thu, 4 Mar 2021 06:18:14 -0800 [thread overview]
Message-ID: <20210304141814.8508-1-baijiaju1990@gmail.com> (raw)
When mlx5_is_fpga_lookaside() returns a non-zero value, no error
return code is assigned.
To fix this bug, err is assigned with -EINVAL as error return code.
