+Subject: [PATCH] brcmfmac: fix wrong num_different_channels when mchan feature
+ enabled
+
+When the device/firmware supports multi-channel, it can have P2P
+connection and regular connection with AP simultaneous. In this case,
+the num_different_channels in wiphy info was not correct when firmware
+supports multi-channel (The iw wiphy# info showed "#channels <= 1" in
+interface combinations). It caused association failed and error message
+"CTRL-EVENT-FREQ-CONFLICT error" in wpa_supplicant when P2P GO interface
+was running at the same time.
+The root cause is that the num_different_channels was always overridden
+to 1 in brcmf_setup_ifmodes even multi-channel was enabled.
+We correct the logic by moving num_different_channels setting forward.
