6.7-stable review patch. If anyone has any objections, please let me know. ------------------ From: Benjamin Berg <benjamin.berg@xxxxxxxxx> [ Upstream commit 32af9a9e1069e55bc02741fb00ac9d0ca1a2eaef ] This is a more of a cosmetic fix. The branch will only be taken if proberesp_ies is set, which implies that beacon_ies is not set unless we are connected to an AP that just did a channel switch. And, in that case we should have found the BSS in the internal storage to begin with.
