ethtool: potential NULL dereference in strset_prepare_data()
Smatch complains that the NULL checking isn't done consistently:
net/ethtool/strset.c:253 strset_prepare_data()
error: we previously assumed 'dev' could be null (see line 233)
It looks like there is a missing return on this path.
Fixes: 71921690f974 ("ethtool: provide string sets with STRSET_GET request")
