syzbot reported a warning from rfkill_alloc(), and after a while I think that the reason is that it was doing fault injection and the dev_set_name() failed, leaving the name NULL, and we didn't check the return value and got to rfkill_alloc() with a NULL name. Since we really don't want a NULL name, we ought to check the return value. Fixes: fb28ad35 ("net: struct device - replace bus_id with dev_name(), dev_set_name()") Reported-by: syzbot+1ddfb3357e1d7bb5b5d3@syzkaller.appspotmail.com Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
