Therefore, we\ncannot check the old_ctx anymore, so we should set it to\nNULL after this point.\n\nHowever, since the new_ctx replace state is clearly not\nIEEE80211_CHANCTX_REPLACES_OTHER, we're not going to do\nanything else in this function and can just return to\navoid accessing the freed old_ctx." |
