+Subject: [PATCH] brcmfmac: move brcmf_bus_preinit() call just after changing
+ bus state
+
+Moving the brcmf_bus_preinit() call allows the bus code to do some
+required initialization before handling firmware control messages.

+Subject: [PATCH] brcmfmac: allocate struct brcmf_pub instance using
+ wiphy_new()
+
+Rework the driver so the wiphy instance holds the main driver information
+in its private buffer. Previously it held struct brcmf_cfg80211_info
+instance so a bit of reorg was needed. This was done so that the wiphy
+name or its parent device can be shown in debug output.
