    nl80211: suppress smatch warnings · 13874e4b
    Johannes Berg authored
    smatch warns that we once checked request->ssids in two functions
    and then unconditionally used it later again.
    This is actually fine, because the code has a relationship between
    attrs[NL80211_ATTR_SCAN_SSIDS], n_ssids and request->ssids, but
    smatch isn't smart enough to realize that.
    Suppress the warnings by always checking just n_ssids - that way
    smatch won't know that request->ssids could be NULL, and since it
    is only NULL when n_ssids is 0 we still check everything correctly.
