This doesn't explain the build failure.

Using ->open() and friends should work perfectly fine for drivers not
yet converted to netdev_ops.  The code protected by COMPAT_NET_DEV_OPS
provides this, and we force that Kconfig option to always be on.

I don't want to add this patch and just shrug off this build failure.
If this build failures, we should be seeing 200 other drivers not
build too.

I suspect something is messed up with this person's kernel config
or similar.
