+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.

+ 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.
