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: move allocation of control rx buffer to
brcmf_sdio_bus_preinit()
Allocate the control rx buffer needed for firmware control interface
during brcmf_sdio_bus_preinit(). This relies on common layer setting
struct brcmf_bus::maxctl during brcmf_attach(). By moving the allocation
we can move brcmf_attach() in subsequent change.

Subject: [PATCH] brcmfmac: call brcmf_attach() just before calling
brcmf_bus_started()
Now we can move brcmf_attach() until after the firmware has been downloaded
to the device. Make the call just before brcmf_bus_started().

Subject: [PATCH] brcmfmac: remove duplicate pointer variable from
brcmf_sdio_firmware_callback()
In brcmf_sdio_firmware_callback() two pointer variables were used
pointing to the same construct. Get rid of sdiodev variable.
