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.
