Jakub,

You probably doesn't have latest net-next.

In the commit 17a7612b99e6 ("net/mlx5_core: Clean driver version and
name"), I removed "strlcpy(drvinfo->version, UTS_RELEASE,
sizeof(drvinfo->version));" line.

The patch is ok, but should have Fixes line.
Fixes: 17a7612b99e6 ("net/mlx5_core: Clean driver version and name")

Thanks
