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.
