[PATCHv5] wlcore: add wl1285 compatible

[PATCH net] Fix an intermittent pr_emerg warning about lo becoming free.

It looks like this: Message from syslogd@flamingo at Apr 26 00:45:00 ... kernel:unregister_netdevice: waiting for lo to become free. Usage count = 4 They seem to coincide with net namespace teardown. The message is emitted by netdev_wait_allrefs(). Forced a kdump in netdev_run_todo, but found
